Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25312, here are decompositions:

  • 3 + 25309 = 25312
  • 5 + 25307 = 25312
  • 11 + 25301 = 25312
  • 59 + 25253 = 25312
  • 83 + 25229 = 25312
  • 149 + 25163 = 25312
  • 191 + 25121 = 25312
  • 239 + 25073 = 25312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25312 first appears in π at position 164,425 of the decimal expansion (the 164,425ordinal-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.
