Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27966, here are decompositions:

  • 5 + 27961 = 27966
  • 13 + 27953 = 27966
  • 19 + 27947 = 27966
  • 23 + 27943 = 27966
  • 47 + 27919 = 27966
  • 73 + 27893 = 27966
  • 83 + 27883 = 27966
  • 139 + 27827 = 27966

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27966 first appears in π at position 10,006 of the decimal expansion (the 10,006ordinal-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.
