Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15696, here are decompositions:

  • 13 + 15683 = 15696
  • 17 + 15679 = 15696
  • 29 + 15667 = 15696
  • 47 + 15649 = 15696
  • 53 + 15643 = 15696
  • 67 + 15629 = 15696
  • 89 + 15607 = 15696
  • 113 + 15583 = 15696

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15696 first appears in π at position 12,533 of the decimal expansion (the 12,533ordinal-suffix:rd 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.
