Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22090, here are decompositions:

  • 11 + 22079 = 22090
  • 17 + 22073 = 22090
  • 23 + 22067 = 22090
  • 53 + 22037 = 22090
  • 59 + 22031 = 22090
  • 113 + 21977 = 22090
  • 179 + 21911 = 22090
  • 197 + 21893 = 22090

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22090 first appears in π at position 45,681 of the decimal expansion (the 45,681ordinal-suffix:st 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.
