Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22912, here are decompositions:

  • 5 + 22907 = 22912
  • 11 + 22901 = 22912
  • 41 + 22871 = 22912
  • 53 + 22859 = 22912
  • 59 + 22853 = 22912
  • 101 + 22811 = 22912
  • 173 + 22739 = 22912
  • 191 + 22721 = 22912

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22912 first appears in π at position 165,588 of the decimal expansion (the 165,588ordinal-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.
