Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31376, here are decompositions:

  • 19 + 31357 = 31376
  • 43 + 31333 = 31376
  • 109 + 31267 = 31376
  • 127 + 31249 = 31376
  • 139 + 31237 = 31376
  • 157 + 31219 = 31376
  • 193 + 31183 = 31376
  • 199 + 31177 = 31376

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31376 first appears in π at position 44,441 of the decimal expansion (the 44,441ordinal-suffix:st 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.
