Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8772, here are decompositions:
- 11 + 8761 = 8772
- 19 + 8753 = 8772
- 31 + 8741 = 8772
- 41 + 8731 = 8772
- 53 + 8719 = 8772
- 59 + 8713 = 8772
- 73 + 8699 = 8772
- 79 + 8693 = 8772
Showing the first eight; more decompositions exist.

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 8772 first appears in π at position 5,994 of the decimal expansion (the 5,994ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
