Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38646, here are decompositions:

  • 7 + 38639 = 38646
  • 17 + 38629 = 38646
  • 37 + 38609 = 38646
  • 43 + 38603 = 38646
  • 53 + 38593 = 38646
  • 79 + 38567 = 38646
  • 89 + 38557 = 38646
  • 103 + 38543 = 38646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38646 first appears in π at position 84,535 of the decimal expansion (the 84,535ordinal-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.
