Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468782, here are decompositions:

  • 3 + 2147468779 = 2147468782
  • 29 + 2147468753 = 2147468782
  • 131 + 2147468651 = 2147468782
  • 191 + 2147468591 = 2147468782
  • 353 + 2147468429 = 2147468782
  • 359 + 2147468423 = 2147468782
  • 491 + 2147468291 = 2147468782
  • 593 + 2147468189 = 2147468782

Showing the first eight; more decompositions exist.
