Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38864, here are decompositions:

  • 3 + 38861 = 38864
  • 13 + 38851 = 38864
  • 31 + 38833 = 38864
  • 43 + 38821 = 38864
  • 61 + 38803 = 38864
  • 73 + 38791 = 38864
  • 97 + 38767 = 38864
  • 127 + 38737 = 38864

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38864 first appears in π at position 260,593 of the decimal expansion (the 260,593ordinal-suffix:rd 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.
