Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147543158, here are decompositions:

  • 71 + 2147543087 = 2147543158
  • 149 + 2147543009 = 2147543158
  • 191 + 2147542967 = 2147543158
  • 269 + 2147542889 = 2147543158
  • 281 + 2147542877 = 2147543158
  • 557 + 2147542601 = 2147543158
  • 587 + 2147542571 = 2147543158
  • 599 + 2147542559 = 2147543158

Showing the first eight; more decompositions exist.
