Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41438, here are decompositions:
- 97 + 41341 = 41438
- 139 + 41299 = 41438
- 157 + 41281 = 41438
- 181 + 41257 = 41438
- 211 + 41227 = 41438
- 277 + 41161 = 41438
- 307 + 41131 = 41438
- 421 + 41017 = 41438
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 41438 first appears in π at position 75,298 of the decimal expansion (the 75,298ordinal-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.
