Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147386860, here are decompositions:

  • 7 + 2147386853 = 2147386860
  • 103 + 2147386757 = 2147386860
  • 107 + 2147386753 = 2147386860
  • 127 + 2147386733 = 2147386860
  • 131 + 2147386729 = 2147386860
  • 149 + 2147386711 = 2147386860
  • 173 + 2147386687 = 2147386860
  • 193 + 2147386667 = 2147386860

Showing the first eight; more decompositions exist.
