Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39984, here are decompositions:

  • 5 + 39979 = 39984
  • 13 + 39971 = 39984
  • 31 + 39953 = 39984
  • 47 + 39937 = 39984
  • 83 + 39901 = 39984
  • 97 + 39887 = 39984
  • 101 + 39883 = 39984
  • 107 + 39877 = 39984

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39984 first appears in π at position 14,407 of the decimal expansion (the 14,407ordinal-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.
