Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16822, here are decompositions:

  • 11 + 16811 = 16822
  • 59 + 16763 = 16822
  • 131 + 16691 = 16822
  • 149 + 16673 = 16822
  • 173 + 16649 = 16822
  • 191 + 16631 = 16822
  • 269 + 16553 = 16822
  • 293 + 16529 = 16822

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16822 first appears in π at position 220,620 of the decimal expansion (the 220,620ordinal-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.
