Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66606, here are decompositions:

  • 5 + 66601 = 66606
  • 13 + 66593 = 66606
  • 19 + 66587 = 66606
  • 37 + 66569 = 66606
  • 53 + 66553 = 66606
  • 73 + 66533 = 66606
  • 83 + 66523 = 66606
  • 97 + 66509 = 66606

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66606 first appears in π at position 320,383 of the decimal expansion (the 320,383ordinal-suffix:rd 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.
