Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9660, here are decompositions:

  • 11 + 9649 = 9660
  • 17 + 9643 = 9660
  • 29 + 9631 = 9660
  • 31 + 9629 = 9660
  • 37 + 9623 = 9660
  • 41 + 9619 = 9660
  • 47 + 9613 = 9660
  • 59 + 9601 = 9660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9660 first appears in π at position 1,330 of the decimal expansion (the 1,330ordinal-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.
