Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66826, here are decompositions:

  • 5 + 66821 = 66826
  • 17 + 66809 = 66826
  • 29 + 66797 = 66826
  • 113 + 66713 = 66826
  • 173 + 66653 = 66826
  • 197 + 66629 = 66826
  • 233 + 66593 = 66826
  • 239 + 66587 = 66826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66826 first appears in π at position 319,624 of the decimal expansion (the 319,624ordinal-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.
