Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17982, here are decompositions:

  • 5 + 17977 = 17982
  • 11 + 17971 = 17982
  • 23 + 17959 = 17982
  • 43 + 17939 = 17982
  • 53 + 17929 = 17982
  • 59 + 17923 = 17982
  • 61 + 17921 = 17982
  • 71 + 17911 = 17982

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17982 first appears in π at position 53,089 of the decimal expansion (the 53,089ordinal-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.
