Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22810, here are decompositions:

  • 3 + 22807 = 22810
  • 23 + 22787 = 22810
  • 41 + 22769 = 22810
  • 59 + 22751 = 22810
  • 71 + 22739 = 22810
  • 83 + 22727 = 22810
  • 89 + 22721 = 22810
  • 101 + 22709 = 22810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22810 first appears in π at position 19,480 of the decimal expansion (the 19,480ordinal-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.
