Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39982, here are decompositions:

  • 3 + 39979 = 39982
  • 11 + 39971 = 39982
  • 29 + 39953 = 39982
  • 53 + 39929 = 39982
  • 113 + 39869 = 39982
  • 191 + 39791 = 39982
  • 233 + 39749 = 39982
  • 263 + 39719 = 39982

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39982 first appears in π at position 42,793 of the decimal expansion (the 42,793ordinal-suffix:rd 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.
