Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526314, here are decompositions:
- 41 + 31526273 = 31526314
- 101 + 31526213 = 31526314
- 107 + 31526207 = 31526314
- 173 + 31526141 = 31526314
- 227 + 31526087 = 31526314
- 251 + 31526063 = 31526314
- 257 + 31526057 = 31526314
- 263 + 31526051 = 31526314
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 1.225.13.170.

The digit sequence 31526314 first appears in π at position 243,299 of the decimal expansion (the 243,299ordinal-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.
