Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10668, here are decompositions:

  • 5 + 10663 = 10668
  • 11 + 10657 = 10668
  • 17 + 10651 = 10668
  • 29 + 10639 = 10668
  • 37 + 10631 = 10668
  • 41 + 10627 = 10668
  • 61 + 10607 = 10668
  • 67 + 10601 = 10668

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10668 first appears in π at position 117,935 of the decimal expansion (the 117,935ordinal-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.
