Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40772, here are decompositions:
- 13 + 40759 = 40772
- 73 + 40699 = 40772
- 79 + 40693 = 40772
- 163 + 40609 = 40772
- 181 + 40591 = 40772
- 229 + 40543 = 40772
- 241 + 40531 = 40772
- 313 + 40459 = 40772
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 40772 first appears in π at position 2,047 of the decimal expansion (the 2,047ordinal-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.
