Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22918, here are decompositions:

  • 11 + 22907 = 22918
  • 17 + 22901 = 22918
  • 41 + 22877 = 22918
  • 47 + 22871 = 22918
  • 59 + 22859 = 22918
  • 101 + 22817 = 22918
  • 107 + 22811 = 22918
  • 131 + 22787 = 22918

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22918 first appears in π at position 107,944 of the decimal expansion (the 107,944ordinal-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.
