$2==9030 is quite precise, compared to /9030/ where 9030 can appear as string or substring in all columns.
Back to the while loop. The read command can split the columns into variables
Sometimes it makes sense to use a case-esac.
The $(( )) can contain a modification of the variable.
BTW here, like in your final awk solution, the $i is not incremented if there is no 1930
(Comment for the experts: bash-2 and ksh88 need i+=1 rather than ++i)

mb_strrpos
MB_STRRPOS(3) 1 MB_STRRPOS(3)mb_strrpos - Find position of last occurrence of a string in a stringSYNOPSIS
int mb_strrpos (string $haystack, string $needle, [int $offset], [string $encoding = mb_internal_encoding()])
DESCRIPTION
Performs a multibyte safe strrpos(3) operation based on the number of characters. $needle position is counted from the beginning of
$haystack. First character's position is 0. Second character position is 1.
PARAMETERS
o $haystack
- The string being checked, for the last occurrence of $needle
o $needle
- The string to find in $haystack.
o $offset
- May be specified to begin searching an arbitrary number of characters into the string. Negative values will stop searching at an
arbitrary point prior to the end of the string.
o $encoding
-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
RETURN VALUES
Returns the numeric position of the last occurrence of $needle in the $haystack string. If $needle is not found, it returns FALSE.

The $encoding parameter was moved from the third position to the fourth in PHP 5.2.0. For backward compatibility, $encoding can be
specified as the third parameter, but doing so is deprecated and will be removed in the future.
