Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66970, here are decompositions:

  • 11 + 66959 = 66970
  • 23 + 66947 = 66970
  • 47 + 66923 = 66970
  • 107 + 66863 = 66970
  • 149 + 66821 = 66970
  • 173 + 66797 = 66970
  • 179 + 66791 = 66970
  • 257 + 66713 = 66970

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66970 first appears in π at position 93,147 of the decimal expansion (the 93,147ordinal-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.
