Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65724, here are decompositions:

  • 5 + 65719 = 65724
  • 7 + 65717 = 65724
  • 11 + 65713 = 65724
  • 17 + 65707 = 65724
  • 23 + 65701 = 65724
  • 37 + 65687 = 65724
  • 47 + 65677 = 65724
  • 67 + 65657 = 65724

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65724 first appears in π at position 25,387 of the decimal expansion (the 25,387ordinal-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.
