Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40442, here are decompositions:
- 13 + 40429 = 40442
- 19 + 40423 = 40442
- 211 + 40231 = 40442
- 229 + 40213 = 40442
- 313 + 40129 = 40442
- 331 + 40111 = 40442
- 349 + 40093 = 40442
- 379 + 40063 = 40442
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 40442 first appears in π at position 97,947 of the decimal expansion (the 97,947ordinal-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.
