Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469148, here are decompositions:

  • 17 + 2147469131 = 2147469148
  • 47 + 2147469101 = 2147469148
  • 59 + 2147469089 = 2147469148
  • 101 + 2147469047 = 2147469148
  • 107 + 2147469041 = 2147469148
  • 131 + 2147469017 = 2147469148
  • 239 + 2147468909 = 2147469148
  • 347 + 2147468801 = 2147469148

Showing the first eight; more decompositions exist.
