Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467690, here are decompositions:

  • 23 + 2147467667 = 2147467690
  • 59 + 2147467631 = 2147467690
  • 107 + 2147467583 = 2147467690
  • 131 + 2147467559 = 2147467690
  • 197 + 2147467493 = 2147467690
  • 227 + 2147467463 = 2147467690
  • 311 + 2147467379 = 2147467690
  • 359 + 2147467331 = 2147467690

Showing the first eight; more decompositions exist.
