Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22690, here are decompositions:

  • 11 + 22679 = 22690
  • 47 + 22643 = 22690
  • 53 + 22637 = 22690
  • 71 + 22619 = 22690
  • 149 + 22541 = 22690
  • 179 + 22511 = 22690
  • 257 + 22433 = 22690
  • 281 + 22409 = 22690

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22690 first appears in π at position 86,541 of the decimal expansion (the 86,541ordinal-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.
