Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404848, here are decompositions:

  • 7 + 2147404841 = 2147404848
  • 19 + 2147404829 = 2147404848
  • 137 + 2147404711 = 2147404848
  • 227 + 2147404621 = 2147404848
  • 229 + 2147404619 = 2147404848
  • 269 + 2147404579 = 2147404848
  • 271 + 2147404577 = 2147404848
  • 359 + 2147404489 = 2147404848

Showing the first eight; more decompositions exist.
