Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27770, here are decompositions:

  • 3 + 27767 = 27770
  • 7 + 27763 = 27770
  • 19 + 27751 = 27770
  • 31 + 27739 = 27770
  • 37 + 27733 = 27770
  • 73 + 27697 = 27770
  • 79 + 27691 = 27770
  • 97 + 27673 = 27770

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27770 first appears in π at position 73,123 of the decimal expansion (the 73,123ordinal-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.
