Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7766, here are decompositions:

  • 7 + 7759 = 7766
  • 13 + 7753 = 7766
  • 43 + 7723 = 7766
  • 67 + 7699 = 7766
  • 79 + 7687 = 7766
  • 97 + 7669 = 7766
  • 127 + 7639 = 7766
  • 163 + 7603 = 7766

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7766 first appears in π at position 890 of the decimal expansion (the 890ordinal-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.
