Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522504, here are decompositions:
- 11 + 31522493 = 31522504
- 53 + 31522451 = 31522504
- 71 + 31522433 = 31522504
- 131 + 31522373 = 31522504
- 173 + 31522331 = 31522504
- 191 + 31522313 = 31522504
- 227 + 31522277 = 31522504
- 257 + 31522247 = 31522504
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 1.224.254.200.
- Address

Public, routable address (assignable to a host on the internet).
The digit sequence 31522504 first appears in π at position 884,226 of the decimal expansion (the 884,226ordinal-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.
