Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469144, here are decompositions:

  • 11 + 2147469133 = 2147469144
  • 13 + 2147469131 = 2147469144
  • 31 + 2147469113 = 2147469144
  • 43 + 2147469101 = 2147469144
  • 71 + 2147469073 = 2147469144
  • 97 + 2147469047 = 2147469144
  • 103 + 2147469041 = 2147469144
  • 127 + 2147469017 = 2147469144

Showing the first eight; more decompositions exist.
