Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469078, here are decompositions:

  • 5 + 2147469073 = 2147469078
  • 11 + 2147469067 = 2147469078
  • 31 + 2147469047 = 2147469078
  • 37 + 2147469041 = 2147469078
  • 61 + 2147469017 = 2147469078
  • 71 + 2147469007 = 2147469078
  • 107 + 2147468971 = 2147469078
  • 191 + 2147468887 = 2147469078

Showing the first eight; more decompositions exist.
