Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22230, here are decompositions:

  • 37 + 22193 = 22230
  • 41 + 22189 = 22230
  • 59 + 22171 = 22230
  • 71 + 22159 = 22230
  • 73 + 22157 = 22230
  • 83 + 22147 = 22230
  • 97 + 22133 = 22230
  • 101 + 22129 = 22230

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22230 first appears in π at position 45,924 of the decimal expansion (the 45,924ordinal-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.
