Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22990, here are decompositions:

  • 17 + 22973 = 22990
  • 29 + 22961 = 22990
  • 47 + 22943 = 22990
  • 53 + 22937 = 22990
  • 83 + 22907 = 22990
  • 89 + 22901 = 22990
  • 113 + 22877 = 22990
  • 131 + 22859 = 22990

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22990 first appears in π at position 200,442 of the decimal expansion (the 200,442ordinal-suffix:nd 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.
