Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38712, here are decompositions:

  • 5 + 38707 = 38712
  • 13 + 38699 = 38712
  • 19 + 38693 = 38712
  • 41 + 38671 = 38712
  • 43 + 38669 = 38712
  • 59 + 38653 = 38712
  • 61 + 38651 = 38712
  • 73 + 38639 = 38712

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38712 first appears in π at position 110,141 of the decimal expansion (the 110,141ordinal-suffix:st 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.
