Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500664, here are decompositions:

  • 3 + 2147500661 = 2147500664
  • 37 + 2147500627 = 2147500664
  • 73 + 2147500591 = 2147500664
  • 103 + 2147500561 = 2147500664
  • 157 + 2147500507 = 2147500664
  • 313 + 2147500351 = 2147500664
  • 367 + 2147500297 = 2147500664
  • 487 + 2147500177 = 2147500664

Showing the first eight; more decompositions exist.
