Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39970, here are decompositions:

  • 17 + 39953 = 39970
  • 41 + 39929 = 39970
  • 83 + 39887 = 39970
  • 101 + 39869 = 39970
  • 107 + 39863 = 39970
  • 113 + 39857 = 39970
  • 131 + 39839 = 39970
  • 149 + 39821 = 39970

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39970 first appears in π at position 182,979 of the decimal expansion (the 182,979ordinal-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.
