Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147464080, here are decompositions:

  • 19 + 2147464061 = 2147464080
  • 31 + 2147464049 = 2147464080
  • 37 + 2147464043 = 2147464080
  • 67 + 2147464013 = 2147464080
  • 71 + 2147464009 = 2147464080
  • 107 + 2147463973 = 2147464080
  • 137 + 2147463943 = 2147464080
  • 163 + 2147463917 = 2147464080

Showing the first eight; more decompositions exist.
