Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17566, here are decompositions:

  • 47 + 17519 = 17566
  • 83 + 17483 = 17566
  • 89 + 17477 = 17566
  • 149 + 17417 = 17566
  • 173 + 17393 = 17566
  • 179 + 17387 = 17566
  • 233 + 17333 = 17566
  • 239 + 17327 = 17566

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17566 first appears in π at position 17,624 of the decimal expansion (the 17,624ordinal-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.
