Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147564622, here are decompositions:

  • 31 + 2147564591 = 2147564622
  • 41 + 2147564581 = 2147564622
  • 53 + 2147564569 = 2147564622
  • 139 + 2147564483 = 2147564622
  • 149 + 2147564473 = 2147564622
  • 241 + 2147564381 = 2147564622
  • 251 + 2147564371 = 2147564622
  • 311 + 2147564311 = 2147564622

Showing the first eight; more decompositions exist.
