Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11660, here are decompositions:

  • 3 + 11657 = 11660
  • 43 + 11617 = 11660
  • 67 + 11593 = 11660
  • 73 + 11587 = 11660
  • 109 + 11551 = 11660
  • 157 + 11503 = 11660
  • 163 + 11497 = 11660
  • 193 + 11467 = 11660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11660 first appears in π at position 3,993 of the decimal expansion (the 3,993ordinal-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.
