Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468790, here are decompositions:

  • 7 + 2147468783 = 2147468790
  • 11 + 2147468779 = 2147468790
  • 17 + 2147468773 = 2147468790
  • 37 + 2147468753 = 2147468790
  • 73 + 2147468717 = 2147468790
  • 139 + 2147468651 = 2147468790
  • 151 + 2147468639 = 2147468790
  • 191 + 2147468599 = 2147468790

Showing the first eight; more decompositions exist.
