Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468802, here are decompositions:

  • 19 + 2147468783 = 2147468802
  • 23 + 2147468779 = 2147468802
  • 29 + 2147468773 = 2147468802
  • 151 + 2147468651 = 2147468802
  • 163 + 2147468639 = 2147468802
  • 181 + 2147468621 = 2147468802
  • 211 + 2147468591 = 2147468802
  • 239 + 2147468563 = 2147468802

Showing the first eight; more decompositions exist.
