Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25710, here are decompositions:

  • 7 + 25703 = 25710
  • 17 + 25693 = 25710
  • 31 + 25679 = 25710
  • 37 + 25673 = 25710
  • 43 + 25667 = 25710
  • 53 + 25657 = 25710
  • 67 + 25643 = 25710
  • 71 + 25639 = 25710

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25710 first appears in π at position 177,373 of the decimal expansion (the 177,373ordinal-suffix:rd 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.
