Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37728, here are decompositions:

  • 11 + 37717 = 37728
  • 29 + 37699 = 37728
  • 37 + 37691 = 37728
  • 71 + 37657 = 37728
  • 79 + 37649 = 37728
  • 109 + 37619 = 37728
  • 137 + 37591 = 37728
  • 139 + 37589 = 37728

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37728 first appears in π at position 38,953 of the decimal expansion (the 38,953ordinal-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.
