Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467866, here are decompositions:

  • 53 + 2147467813 = 2147467866
  • 73 + 2147467793 = 2147467866
  • 97 + 2147467769 = 2147467866
  • 107 + 2147467759 = 2147467866
  • 149 + 2147467717 = 2147467866
  • 197 + 2147467669 = 2147467866
  • 199 + 2147467667 = 2147467866
  • 227 + 2147467639 = 2147467866

Showing the first eight; more decompositions exist.
