Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66938, here are decompositions:

  • 7 + 66931 = 66938
  • 19 + 66919 = 66938
  • 61 + 66877 = 66938
  • 97 + 66841 = 66938
  • 199 + 66739 = 66938
  • 241 + 66697 = 66938
  • 337 + 66601 = 66938
  • 367 + 66571 = 66938

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66938 first appears in π at position 177,622 of the decimal expansion (the 177,622ordinal-suffix:nd 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.
