Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39786, here are decompositions:

  • 7 + 39779 = 39786
  • 17 + 39769 = 39786
  • 37 + 39749 = 39786
  • 53 + 39733 = 39786
  • 59 + 39727 = 39786
  • 67 + 39719 = 39786
  • 83 + 39703 = 39786
  • 107 + 39679 = 39786

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39786 first appears in π at position 595,015 of the decimal expansion (the 595,015ordinal-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.
