Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40918, here are decompositions:
- 71 + 40847 = 40918
- 89 + 40829 = 40918
- 131 + 40787 = 40918
- 167 + 40751 = 40918
- 179 + 40739 = 40918
- 281 + 40637 = 40918
- 359 + 40559 = 40918
- 389 + 40529 = 40918
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 40918 first appears in π at position 9,320 of the decimal expansion (the 9,320ordinal-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.
