Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468824, here are decompositions:

  • 23 + 2147468801 = 2147468824
  • 41 + 2147468783 = 2147468824
  • 71 + 2147468753 = 2147468824
  • 107 + 2147468717 = 2147468824
  • 173 + 2147468651 = 2147468824
  • 233 + 2147468591 = 2147468824
  • 317 + 2147468507 = 2147468824
  • 401 + 2147468423 = 2147468824

Showing the first eight; more decompositions exist.
