Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25118, here are decompositions:

  • 7 + 25111 = 25118
  • 31 + 25087 = 25118
  • 61 + 25057 = 25118
  • 139 + 24979 = 25118
  • 151 + 24967 = 25118
  • 199 + 24919 = 25118
  • 211 + 24907 = 25118
  • 229 + 24889 = 25118

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25118 first appears in π at position 16,273 of the decimal expansion (the 16,273ordinal-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.
