Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500944, here are decompositions:

  • 7 + 2147500937 = 2147500944
  • 13 + 2147500931 = 2147500944
  • 37 + 2147500907 = 2147500944
  • 73 + 2147500871 = 2147500944
  • 131 + 2147500813 = 2147500944
  • 163 + 2147500781 = 2147500944
  • 181 + 2147500763 = 2147500944
  • 283 + 2147500661 = 2147500944

Showing the first eight; more decompositions exist.
