Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17956, here are decompositions:

  • 17 + 17939 = 17956
  • 47 + 17909 = 17956
  • 53 + 17903 = 17956
  • 149 + 17807 = 17956
  • 167 + 17789 = 17956
  • 173 + 17783 = 17956
  • 227 + 17729 = 17956
  • 347 + 17609 = 17956

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17956 first appears in π at position 110,685 of the decimal expansion (the 110,685ordinal-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.
