Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500066, here are decompositions:

  • 3 + 2147500063 = 2147500066
  • 17 + 2147500049 = 2147500066
  • 59 + 2147500007 = 2147500066
  • 113 + 2147499953 = 2147500066
  • 149 + 2147499917 = 2147500066
  • 359 + 2147499707 = 2147500066
  • 449 + 2147499617 = 2147500066
  • 557 + 2147499509 = 2147500066

Showing the first eight; more decompositions exist.
