Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38938, here are decompositions:

  • 5 + 38933 = 38938
  • 17 + 38921 = 38938
  • 47 + 38891 = 38938
  • 71 + 38867 = 38938
  • 191 + 38747 = 38938
  • 227 + 38711 = 38938
  • 239 + 38699 = 38938
  • 269 + 38669 = 38938

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38938 first appears in π at position 315,680 of the decimal expansion (the 315,680ordinal-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.
