Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483856, here are decompositions:

  • 43 + 2147483813 = 2147483856
  • 73 + 2147483783 = 2147483856
  • 79 + 2147483777 = 2147483856
  • 113 + 2147483743 = 2147483856
  • 163 + 2147483693 = 2147483856
  • 197 + 2147483659 = 2147483856
  • 227 + 2147483629 = 2147483856
  • 269 + 2147483587 = 2147483856

Showing the first eight; more decompositions exist.
