Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31716, here are decompositions:

  • 17 + 31699 = 31716
  • 29 + 31687 = 31716
  • 53 + 31663 = 31716
  • 59 + 31657 = 31716
  • 67 + 31649 = 31716
  • 73 + 31643 = 31716
  • 89 + 31627 = 31716
  • 109 + 31607 = 31716

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31716 first appears in π at position 142,631 of the decimal expansion (the 142,631ordinal-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.
