Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468786, here are decompositions:

  • 3 + 2147468783 = 2147468786
  • 7 + 2147468779 = 2147468786
  • 13 + 2147468773 = 2147468786
  • 223 + 2147468563 = 2147468786
  • 283 + 2147468503 = 2147468786
  • 613 + 2147468173 = 2147468786
  • 823 + 2147467963 = 2147468786
  • 1039 + 2147467747 = 2147468786

Showing the first eight; more decompositions exist.
