Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38808, here are decompositions:

  • 5 + 38803 = 38808
  • 17 + 38791 = 38808
  • 41 + 38767 = 38808
  • 59 + 38749 = 38808
  • 61 + 38747 = 38808
  • 71 + 38737 = 38808
  • 79 + 38729 = 38808
  • 97 + 38711 = 38808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38808 first appears in π at position 288,998 of the decimal expansion (the 288,998ordinal-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.
