Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500856, here are decompositions:

  • 43 + 2147500813 = 2147500856
  • 229 + 2147500627 = 2147500856
  • 349 + 2147500507 = 2147500856
  • 673 + 2147500183 = 2147500856
  • 733 + 2147500123 = 2147500856
  • 859 + 2147499997 = 2147500856
  • 1129 + 2147499727 = 2147500856
  • 1153 + 2147499703 = 2147500856

Showing the first eight; more decompositions exist.
