Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500890, here are decompositions:

  • 11 + 2147500879 = 2147500890
  • 19 + 2147500871 = 2147500890
  • 109 + 2147500781 = 2147500890
  • 127 + 2147500763 = 2147500890
  • 167 + 2147500723 = 2147500890
  • 193 + 2147500697 = 2147500890
  • 229 + 2147500661 = 2147500890
  • 263 + 2147500627 = 2147500890

Showing the first eight; more decompositions exist.
