Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426864, here are decompositions:

  • 43 + 2147426821 = 2147426864
  • 223 + 2147426641 = 2147426864
  • 241 + 2147426623 = 2147426864
  • 307 + 2147426557 = 2147426864
  • 313 + 2147426551 = 2147426864
  • 337 + 2147426527 = 2147426864
  • 367 + 2147426497 = 2147426864
  • 397 + 2147426467 = 2147426864

Showing the first eight; more decompositions exist.
