Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36640, here are decompositions:

  • 3 + 36637 = 36640
  • 11 + 36629 = 36640
  • 41 + 36599 = 36640
  • 53 + 36587 = 36640
  • 89 + 36551 = 36640
  • 113 + 36527 = 36640
  • 167 + 36473 = 36640
  • 173 + 36467 = 36640

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 36640 first appears in π at position 24,717 of the decimal expansion (the 24,717ordinal-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.
