Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40426, here are decompositions:
- 3 + 40423 = 40426
- 83 + 40343 = 40426
- 137 + 40289 = 40426
- 149 + 40277 = 40426
- 173 + 40253 = 40426
- 233 + 40193 = 40426
- 257 + 40169 = 40426
- 263 + 40163 = 40426
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 40426 first appears in π at position 291,633 of the decimal expansion (the 291,633ordinal-suffix:rd 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.
