Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467986, here are decompositions:

  • 19 + 2147467967 = 2147467986
  • 23 + 2147467963 = 2147467986
  • 67 + 2147467919 = 2147467986
  • 173 + 2147467813 = 2147467986
  • 193 + 2147467793 = 2147467986
  • 227 + 2147467759 = 2147467986
  • 239 + 2147467747 = 2147467986
  • 269 + 2147467717 = 2147467986

Showing the first eight; more decompositions exist.
