Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25910, here are decompositions:

  • 7 + 25903 = 25910
  • 37 + 25873 = 25910
  • 43 + 25867 = 25910
  • 61 + 25849 = 25910
  • 109 + 25801 = 25910
  • 139 + 25771 = 25910
  • 151 + 25759 = 25910
  • 163 + 25747 = 25910

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25910 first appears in π at position 150,645 of the decimal expansion (the 150,645ordinal-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.
