Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22186, here are decompositions:

  • 29 + 22157 = 22186
  • 53 + 22133 = 22186
  • 107 + 22079 = 22186
  • 113 + 22073 = 22186
  • 149 + 22037 = 22186
  • 173 + 22013 = 22186
  • 257 + 21929 = 22186
  • 293 + 21893 = 22186

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22186 first appears in π at position 64,088 of the decimal expansion (the 64,088ordinal-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.
