Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36810, here are decompositions:

  • 17 + 36793 = 36810
  • 19 + 36791 = 36810
  • 23 + 36787 = 36810
  • 29 + 36781 = 36810
  • 31 + 36779 = 36810
  • 43 + 36767 = 36810
  • 61 + 36749 = 36810
  • 71 + 36739 = 36810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 36810 first appears in π at position 131,786 of the decimal expansion (the 131,786ordinal-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.
