Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10690, here are decompositions:

  • 3 + 10687 = 10690
  • 23 + 10667 = 10690
  • 59 + 10631 = 10690
  • 83 + 10607 = 10690
  • 89 + 10601 = 10690
  • 101 + 10589 = 10690
  • 131 + 10559 = 10690
  • 191 + 10499 = 10690

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10690 first appears in π at position 259,327 of the decimal expansion (the 259,327ordinal-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.
