Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65712, here are decompositions:

  • 5 + 65707 = 65712
  • 11 + 65701 = 65712
  • 13 + 65699 = 65712
  • 61 + 65651 = 65712
  • 79 + 65633 = 65712
  • 83 + 65629 = 65712
  • 103 + 65609 = 65712
  • 113 + 65599 = 65712

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65712 first appears in π at position 4,725 of the decimal expansion (the 4,725ordinal-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.
