Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87764, here are decompositions:
- 13 + 87751 = 87764
- 43 + 87721 = 87764
- 67 + 87697 = 87764
- 73 + 87691 = 87764
- 151 + 87613 = 87764
- 181 + 87583 = 87764
- 211 + 87553 = 87764
- 223 + 87541 = 87764
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.86.212.

- IPv4-mapped IPv6
- ::ffff:0.1.86.212
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 87764 first appears in π at position 170,354 of the decimal expansion (the 170,354ordinal-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.
