Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467784, here are decompositions:

  • 37 + 2147467747 = 2147467784
  • 67 + 2147467717 = 2147467784
  • 73 + 2147467711 = 2147467784
  • 157 + 2147467627 = 2147467784
  • 313 + 2147467471 = 2147467784
  • 457 + 2147467327 = 2147467784
  • 463 + 2147467321 = 2147467784
  • 523 + 2147467261 = 2147467784

Showing the first eight; more decompositions exist.
