Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40810, here are decompositions:

  • 23 + 40787 = 40810
  • 47 + 40763 = 40810
  • 59 + 40751 = 40810
  • 71 + 40739 = 40810
  • 101 + 40709 = 40810
  • 113 + 40697 = 40810
  • 173 + 40637 = 40810
  • 227 + 40583 = 40810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40810 first appears in π at position 111,208 of the decimal expansion (the 111,208ordinal-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.
