Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22168, here are decompositions:

  • 11 + 22157 = 22168
  • 59 + 22109 = 22168
  • 89 + 22079 = 22168
  • 101 + 22067 = 22168
  • 131 + 22037 = 22168
  • 137 + 22031 = 22168
  • 191 + 21977 = 22168
  • 239 + 21929 = 22168

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22168 first appears in π at position 5,150 of the decimal expansion (the 5,150ordinal-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.
