Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17586, here are decompositions:

  • 5 + 17581 = 17586
  • 7 + 17579 = 17586
  • 13 + 17573 = 17586
  • 17 + 17569 = 17586
  • 47 + 17539 = 17586
  • 67 + 17519 = 17586
  • 89 + 17497 = 17586
  • 97 + 17489 = 17586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17586 first appears in π at position 105,263 of the decimal expansion (the 105,263ordinal-suffix:rd 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.
