Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483904, here are decompositions:

  • 11 + 2147483893 = 2147483904
  • 17 + 2147483887 = 2147483904
  • 37 + 2147483867 = 2147483904
  • 47 + 2147483857 = 2147483904
  • 127 + 2147483777 = 2147483904
  • 191 + 2147483713 = 2147483904
  • 211 + 2147483693 = 2147483904
  • 257 + 2147483647 = 2147483904

Showing the first eight; more decompositions exist.
