Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467816, here are decompositions:

  • 3 + 2147467813 = 2147467816
  • 23 + 2147467793 = 2147467816
  • 47 + 2147467769 = 2147467816
  • 83 + 2147467733 = 2147467816
  • 149 + 2147467667 = 2147467816
  • 233 + 2147467583 = 2147467816
  • 257 + 2147467559 = 2147467816
  • 353 + 2147467463 = 2147467816

Showing the first eight; more decompositions exist.
