Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483888, here are decompositions:

  • 19 + 2147483869 = 2147483888
  • 31 + 2147483857 = 2147483888
  • 229 + 2147483659 = 2147483888
  • 241 + 2147483647 = 2147483888
  • 619 + 2147483269 = 2147483888
  • 709 + 2147483179 = 2147483888
  • 751 + 2147483137 = 2147483888
  • 811 + 2147483077 = 2147483888

Showing the first eight; more decompositions exist.
