Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22390, here are decompositions:

  • 23 + 22367 = 22390
  • 41 + 22349 = 22390
  • 47 + 22343 = 22390
  • 83 + 22307 = 22390
  • 107 + 22283 = 22390
  • 113 + 22277 = 22390
  • 131 + 22259 = 22390
  • 197 + 22193 = 22390

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22390 first appears in π at position 62,681 of the decimal expansion (the 62,681ordinal-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.
