Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43012, here are decompositions:
- 23 + 42989 = 43012
- 59 + 42953 = 43012
- 83 + 42929 = 43012
- 89 + 42923 = 43012
- 113 + 42899 = 43012
- 149 + 42863 = 43012
- 173 + 42839 = 43012
- 191 + 42821 = 43012
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 43012 first appears in π at position 61,340 of the decimal expansion (the 61,340ordinal-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.
