Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422932, here are decompositions:

  • 41 + 2147422891 = 2147422932
  • 59 + 2147422873 = 2147422932
  • 71 + 2147422861 = 2147422932
  • 113 + 2147422819 = 2147422932
  • 229 + 2147422703 = 2147422932
  • 241 + 2147422691 = 2147422932
  • 269 + 2147422663 = 2147422932
  • 283 + 2147422649 = 2147422932

Showing the first eight; more decompositions exist.
