Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426048, here are decompositions:

  • 337 + 2147425711 = 2147426048
  • 367 + 2147425681 = 2147426048
  • 457 + 2147425591 = 2147426048
  • 541 + 2147425507 = 2147426048
  • 601 + 2147425447 = 2147426048
  • 739 + 2147425309 = 2147426048
  • 751 + 2147425297 = 2147426048
  • 811 + 2147425237 = 2147426048

Showing the first eight; more decompositions exist.
