Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500818, here are decompositions:

  • 5 + 2147500813 = 2147500818
  • 37 + 2147500781 = 2147500818
  • 157 + 2147500661 = 2147500818
  • 191 + 2147500627 = 2147500818
  • 227 + 2147500591 = 2147500818
  • 257 + 2147500561 = 2147500818
  • 311 + 2147500507 = 2147500818
  • 457 + 2147500361 = 2147500818

Showing the first eight; more decompositions exist.
