Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573374, here are decompositions:

  • 11 + 31573363 = 31573374
  • 13 + 31573361 = 31573374
  • 17 + 31573357 = 31573374
  • 97 + 31573277 = 31573374
  • 113 + 31573261 = 31573374
  • 163 + 31573211 = 31573374
  • 211 + 31573163 = 31573374
  • 223 + 31573151 = 31573374

Showing the first eight; more decompositions exist.

Public, routable address (assignable to a host on the internet).

Position in π

The digit sequence 31573374 first appears in π at position 13,964 of the decimal expansion (the 13,964ordinal-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.
