Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39684, here are decompositions:

  • 5 + 39679 = 39684
  • 13 + 39671 = 39684
  • 17 + 39667 = 39684
  • 53 + 39631 = 39684
  • 61 + 39623 = 39684
  • 103 + 39581 = 39684
  • 163 + 39521 = 39684
  • 173 + 39511 = 39684

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39684 first appears in π at position 129,169 of the decimal expansion (the 129,169ordinal-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.
