Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27512, here are decompositions:

  • 3 + 27509 = 27512
  • 31 + 27481 = 27512
  • 103 + 27409 = 27512
  • 151 + 27361 = 27512
  • 229 + 27283 = 27512
  • 241 + 27271 = 27512
  • 271 + 27241 = 27512
  • 409 + 27103 = 27512

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27512 first appears in π at position 192,759 of the decimal expansion (the 192,759ordinal-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.
