Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17690, here are decompositions:

  • 7 + 17683 = 17690
  • 31 + 17659 = 17690
  • 67 + 17623 = 17690
  • 109 + 17581 = 17690
  • 139 + 17551 = 17690
  • 151 + 17539 = 17690
  • 181 + 17509 = 17690
  • 193 + 17497 = 17690

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17690 first appears in π at position 31,740 of the decimal expansion (the 31,740ordinal-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.
