Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19922, here are decompositions:

  • 3 + 19919 = 19922
  • 31 + 19891 = 19922
  • 61 + 19861 = 19922
  • 79 + 19843 = 19922
  • 103 + 19819 = 19922
  • 109 + 19813 = 19922
  • 163 + 19759 = 19922
  • 223 + 19699 = 19922

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19922 first appears in π at position 20,499 of the decimal expansion (the 20,499ordinal-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.
