Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87476, here are decompositions:
- 3 + 87473 = 87476
- 43 + 87433 = 87476
- 73 + 87403 = 87476
- 139 + 87337 = 87476
- 163 + 87313 = 87476
- 199 + 87277 = 87476
- 223 + 87253 = 87476
- 373 + 87103 = 87476
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.85.180.

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 87476 first appears in π at position 2,584 of the decimal expansion (the 2,584ordinal-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.
