Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86646, here are decompositions:

  • 17 + 86629 = 86646
  • 19 + 86627 = 86646
  • 47 + 86599 = 86646
  • 59 + 86587 = 86646
  • 67 + 86579 = 86646
  • 73 + 86573 = 86646
  • 107 + 86539 = 86646
  • 113 + 86533 = 86646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86646 first appears in π at position 38,238 of the decimal expansion (the 38,238ordinal-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.
