Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468748, here are decompositions:

  • 31 + 2147468717 = 2147468748
  • 97 + 2147468651 = 2147468748
  • 109 + 2147468639 = 2147468748
  • 127 + 2147468621 = 2147468748
  • 149 + 2147468599 = 2147468748
  • 157 + 2147468591 = 2147468748
  • 211 + 2147468537 = 2147468748
  • 241 + 2147468507 = 2147468748

Showing the first eight; more decompositions exist.
