Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426912, here are decompositions:

  • 271 + 2147426641 = 2147426912
  • 283 + 2147426629 = 2147426912
  • 691 + 2147426221 = 2147426912
  • 751 + 2147426161 = 2147426912
  • 769 + 2147426143 = 2147426912
  • 859 + 2147426053 = 2147426912
  • 919 + 2147425993 = 2147426912
  • 1033 + 2147425879 = 2147426912

Showing the first eight; more decompositions exist.
