Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497944, here are decompositions:

  • 5 + 2147497939 = 2147497944
  • 23 + 2147497921 = 2147497944
  • 37 + 2147497907 = 2147497944
  • 43 + 2147497901 = 2147497944
  • 173 + 2147497771 = 2147497944
  • 211 + 2147497733 = 2147497944
  • 227 + 2147497717 = 2147497944
  • 281 + 2147497663 = 2147497944

Showing the first eight; more decompositions exist.
