Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40264, here are decompositions:
- 11 + 40253 = 40264
- 23 + 40241 = 40264
- 71 + 40193 = 40264
- 101 + 40163 = 40264
- 113 + 40151 = 40264
- 137 + 40127 = 40264
- 227 + 40037 = 40264
- 233 + 40031 = 40264
Showing the first eight; more decompositions exist.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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 40264 first appears in π at position 91,334 of the decimal expansion (the 91,334ordinal-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.
