Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502546, here are decompositions:
- 7 + 31502539 = 31502546
- 13 + 31502533 = 31502546
- 193 + 31502353 = 31502546
- 277 + 31502269 = 31502546
- 433 + 31502113 = 31502546
- 463 + 31502083 = 31502546
- 727 + 31501819 = 31502546
- 739 + 31501807 = 31502546
Showing the first eight; more decompositions exist.

Public, routable address (assignable to a host on the internet).
The digit sequence 31502546 first appears in π at position 110,578 of the decimal expansion (the 110,578ordinal-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.
