Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66822, here are decompositions:

  • 13 + 66809 = 66822
  • 31 + 66791 = 66822
  • 59 + 66763 = 66822
  • 71 + 66751 = 66822
  • 73 + 66749 = 66822
  • 83 + 66739 = 66822
  • 89 + 66733 = 66822
  • 101 + 66721 = 66822

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66822 first appears in π at position 259,641 of the decimal expansion (the 259,641ordinal-suffix:st 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.
