Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468758, here are decompositions:

  • 5 + 2147468753 = 2147468758
  • 41 + 2147468717 = 2147468758
  • 107 + 2147468651 = 2147468758
  • 137 + 2147468621 = 2147468758
  • 167 + 2147468591 = 2147468758
  • 251 + 2147468507 = 2147468758
  • 467 + 2147468291 = 2147468758
  • 509 + 2147468249 = 2147468758

Showing the first eight; more decompositions exist.
