Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38718, here are decompositions:

  • 5 + 38713 = 38718
  • 7 + 38711 = 38718
  • 11 + 38707 = 38718
  • 19 + 38699 = 38718
  • 41 + 38677 = 38718
  • 47 + 38671 = 38718
  • 67 + 38651 = 38718
  • 79 + 38639 = 38718

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38718 first appears in π at position 180,727 of the decimal expansion (the 180,727ordinal-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.
