Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66782, here are decompositions:

  • 19 + 66763 = 66782
  • 31 + 66751 = 66782
  • 43 + 66739 = 66782
  • 61 + 66721 = 66782
  • 139 + 66643 = 66782
  • 181 + 66601 = 66782
  • 211 + 66571 = 66782
  • 229 + 66553 = 66782

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66782 first appears in π at position 171,666 of the decimal expansion (the 171,666ordinal-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.
