Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712, here are decompositions:

  • 5 + 8707 = 8712
  • 13 + 8699 = 8712
  • 19 + 8693 = 8712
  • 23 + 8689 = 8712
  • 31 + 8681 = 8712
  • 43 + 8669 = 8712
  • 71 + 8641 = 8712
  • 83 + 8629 = 8712

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8712 first appears in π at position 8,166 of the decimal expansion (the 8,166ordinal-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.
