Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468822, here are decompositions:

  • 13 + 2147468809 = 2147468822
  • 19 + 2147468803 = 2147468822
  • 43 + 2147468779 = 2147468822
  • 223 + 2147468599 = 2147468822
  • 379 + 2147468443 = 2147468822
  • 691 + 2147468131 = 2147468822
  • 859 + 2147467963 = 2147468822
  • 1009 + 2147467813 = 2147468822

Showing the first eight; more decompositions exist.
