Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467894, here are decompositions:

  • 23 + 2147467871 = 2147467894
  • 101 + 2147467793 = 2147467894
  • 197 + 2147467697 = 2147467894
  • 227 + 2147467667 = 2147467894
  • 263 + 2147467631 = 2147467894
  • 311 + 2147467583 = 2147467894
  • 401 + 2147467493 = 2147467894
  • 431 + 2147467463 = 2147467894

Showing the first eight; more decompositions exist.
