Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467686, here are decompositions:

  • 17 + 2147467669 = 2147467686
  • 19 + 2147467667 = 2147467686
  • 47 + 2147467639 = 2147467686
  • 59 + 2147467627 = 2147467686
  • 103 + 2147467583 = 2147467686
  • 107 + 2147467579 = 2147467686
  • 127 + 2147467559 = 2147467686
  • 193 + 2147467493 = 2147467686

Showing the first eight; more decompositions exist.
