Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66930, here are decompositions:

  • 7 + 66923 = 66930
  • 11 + 66919 = 66930
  • 41 + 66889 = 66930
  • 47 + 66883 = 66930
  • 53 + 66877 = 66930
  • 67 + 66863 = 66930
  • 79 + 66851 = 66930
  • 89 + 66841 = 66930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66930 first appears in π at position 21,087 of the decimal expansion (the 21,087ordinal-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.
