Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468658, here are decompositions:

  • 7 + 2147468651 = 2147468658
  • 19 + 2147468639 = 2147468658
  • 37 + 2147468621 = 2147468658
  • 59 + 2147468599 = 2147468658
  • 67 + 2147468591 = 2147468658
  • 151 + 2147468507 = 2147468658
  • 227 + 2147468431 = 2147468658
  • 229 + 2147468429 = 2147468658

Showing the first eight; more decompositions exist.
