Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87340, here are decompositions:
- 3 + 87337 = 87340
- 17 + 87323 = 87340
- 23 + 87317 = 87340
- 41 + 87299 = 87340
- 47 + 87293 = 87340
- 59 + 87281 = 87340
- 83 + 87257 = 87340
- 89 + 87251 = 87340
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.85.44.
- Address
- 0.1.85.44

- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.85.44
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 87340 first appears in π at position 363,902 of the decimal expansion (the 363,902ordinal-suffix:nd 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.
