Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25186, here are decompositions:

  • 3 + 25183 = 25186
  • 17 + 25169 = 25186
  • 23 + 25163 = 25186
  • 59 + 25127 = 25186
  • 89 + 25097 = 25186
  • 113 + 25073 = 25186
  • 149 + 25037 = 25186
  • 173 + 25013 = 25186

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25186 first appears in π at position 3,147 of the decimal expansion (the 3,147ordinal-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.
