Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469154, here are decompositions:

  • 23 + 2147469131 = 2147469154
  • 41 + 2147469113 = 2147469154
  • 53 + 2147469101 = 2147469154
  • 107 + 2147469047 = 2147469154
  • 113 + 2147469041 = 2147469154
  • 137 + 2147469017 = 2147469154
  • 167 + 2147468987 = 2147469154
  • 293 + 2147468861 = 2147469154

Showing the first eight; more decompositions exist.
