Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31654, here are decompositions:

  • 5 + 31649 = 31654
  • 11 + 31643 = 31654
  • 47 + 31607 = 31654
  • 53 + 31601 = 31654
  • 71 + 31583 = 31654
  • 107 + 31547 = 31654
  • 113 + 31541 = 31654
  • 137 + 31517 = 31654

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31654 first appears in π at position 93,556 of the decimal expansion (the 93,556ordinal-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.
