Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500902, here are decompositions:

  • 13 + 2147500889 = 2147500902
  • 23 + 2147500879 = 2147500902
  • 31 + 2147500871 = 2147500902
  • 89 + 2147500813 = 2147500902
  • 139 + 2147500763 = 2147500902
  • 179 + 2147500723 = 2147500902
  • 241 + 2147500661 = 2147500902
  • 311 + 2147500591 = 2147500902

Showing the first eight; more decompositions exist.
