Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500868, here are decompositions:

  • 241 + 2147500627 = 2147500868
  • 277 + 2147500591 = 2147500868
  • 307 + 2147500561 = 2147500868
  • 571 + 2147500297 = 2147500868
  • 691 + 2147500177 = 2147500868
  • 757 + 2147500111 = 2147500868
  • 787 + 2147500081 = 2147500868
  • 907 + 2147499961 = 2147500868

Showing the first eight; more decompositions exist.
