Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25750, here are decompositions:

  • 3 + 25747 = 25750
  • 17 + 25733 = 25750
  • 47 + 25703 = 25750
  • 71 + 25679 = 25750
  • 83 + 25667 = 25750
  • 107 + 25643 = 25750
  • 149 + 25601 = 25750
  • 167 + 25583 = 25750

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25750 first appears in π at position 17,705 of the decimal expansion (the 17,705ordinal-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.
