Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7730, here are decompositions:

  • 3 + 7727 = 7730
  • 7 + 7723 = 7730
  • 13 + 7717 = 7730
  • 31 + 7699 = 7730
  • 43 + 7687 = 7730
  • 61 + 7669 = 7730
  • 109 + 7621 = 7730
  • 127 + 7603 = 7730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7730 first appears in π at position 20,719 of the decimal expansion (the 20,719ordinal-suffix:th 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.
