Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38790, here are decompositions:

  • 7 + 38783 = 38790
  • 23 + 38767 = 38790
  • 41 + 38749 = 38790
  • 43 + 38747 = 38790
  • 53 + 38737 = 38790
  • 61 + 38729 = 38790
  • 67 + 38723 = 38790
  • 79 + 38711 = 38790

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38790 first appears in π at position 73,881 of the decimal expansion (the 73,881ordinal-suffix:st 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.
