Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500568, here are decompositions:

  • 7 + 2147500561 = 2147500568
  • 61 + 2147500507 = 2147500568
  • 229 + 2147500339 = 2147500568
  • 271 + 2147500297 = 2147500568
  • 457 + 2147500111 = 2147500568
  • 487 + 2147500081 = 2147500568
  • 571 + 2147499997 = 2147500568
  • 607 + 2147499961 = 2147500568

Showing the first eight; more decompositions exist.
