Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17992, here are decompositions:

  • 3 + 17989 = 17992
  • 5 + 17987 = 17992
  • 11 + 17981 = 17992
  • 53 + 17939 = 17992
  • 71 + 17921 = 17992
  • 83 + 17909 = 17992
  • 89 + 17903 = 17992
  • 101 + 17891 = 17992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17992 first appears in π at position 19,222 of the decimal expansion (the 19,222ordinal-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.
