Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64768, here are decompositions:

  • 5 + 64763 = 64768
  • 59 + 64709 = 64768
  • 89 + 64679 = 64768
  • 101 + 64667 = 64768
  • 107 + 64661 = 64768
  • 167 + 64601 = 64768
  • 191 + 64577 = 64768
  • 269 + 64499 = 64768

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64768 first appears in π at position 39,103 of the decimal expansion (the 39,103ordinal-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.
