Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443764, here are decompositions:

  • 5 + 2147443759 = 2147443764
  • 17 + 2147443747 = 2147443764
  • 43 + 2147443721 = 2147443764
  • 131 + 2147443633 = 2147443764
  • 197 + 2147443567 = 2147443764
  • 227 + 2147443537 = 2147443764
  • 241 + 2147443523 = 2147443764
  • 251 + 2147443513 = 2147443764

Showing the first eight; more decompositions exist.
