Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468944, here are decompositions:

  • 11 + 2147468933 = 2147468944
  • 83 + 2147468861 = 2147468944
  • 191 + 2147468753 = 2147468944
  • 227 + 2147468717 = 2147468944
  • 293 + 2147468651 = 2147468944
  • 353 + 2147468591 = 2147468944
  • 521 + 2147468423 = 2147468944
  • 653 + 2147468291 = 2147468944

Showing the first eight; more decompositions exist.
