Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22200, here are decompositions:

  • 7 + 22193 = 22200
  • 11 + 22189 = 22200
  • 29 + 22171 = 22200
  • 41 + 22159 = 22200
  • 43 + 22157 = 22200
  • 47 + 22153 = 22200
  • 53 + 22147 = 22200
  • 67 + 22133 = 22200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22200 first appears in π at position 216,661 of the decimal expansion (the 216,661ordinal-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.
