Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31776, here are decompositions:

  • 5 + 31771 = 31776
  • 7 + 31769 = 31776
  • 47 + 31729 = 31776
  • 53 + 31723 = 31776
  • 89 + 31687 = 31776
  • 109 + 31667 = 31776
  • 113 + 31663 = 31776
  • 127 + 31649 = 31776

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31776 first appears in π at position 126,680 of the decimal expansion (the 126,680ordinal-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.
