Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25200, here are decompositions:

  • 11 + 25189 = 25200
  • 17 + 25183 = 25200
  • 29 + 25171 = 25200
  • 31 + 25169 = 25200
  • 37 + 25163 = 25200
  • 47 + 25153 = 25200
  • 53 + 25147 = 25200
  • 73 + 25127 = 25200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25200 first appears in π at position 71,018 of the decimal expansion (the 71,018ordinal-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.
