Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25708, here are decompositions:

  • 5 + 25703 = 25708
  • 29 + 25679 = 25708
  • 41 + 25667 = 25708
  • 107 + 25601 = 25708
  • 131 + 25577 = 25708
  • 167 + 25541 = 25708
  • 239 + 25469 = 25708
  • 251 + 25457 = 25708

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25708 first appears in π at position 72,386 of the decimal expansion (the 72,386ordinal-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.
