Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25766, here are decompositions:

  • 3 + 25763 = 25766
  • 7 + 25759 = 25766
  • 19 + 25747 = 25766
  • 73 + 25693 = 25766
  • 109 + 25657 = 25766
  • 127 + 25639 = 25766
  • 157 + 25609 = 25766
  • 163 + 25603 = 25766

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25766 first appears in π at position 114,297 of the decimal expansion (the 114,297ordinal-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.
