Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68170, here are decompositions:

  • 23 + 68147 = 68170
  • 29 + 68141 = 68170
  • 59 + 68111 = 68170
  • 71 + 68099 = 68170
  • 83 + 68087 = 68170
  • 191 + 67979 = 68170
  • 227 + 67943 = 68170
  • 239 + 67931 = 68170

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68170 first appears in π at position 69,453 of the decimal expansion (the 69,453ordinal-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.
