Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448388, here are decompositions:

  • 101 + 2147448287 = 2147448388
  • 131 + 2147448257 = 2147448388
  • 191 + 2147448197 = 2147448388
  • 317 + 2147448071 = 2147448388
  • 401 + 2147447987 = 2147448388
  • 641 + 2147447747 = 2147448388
  • 719 + 2147447669 = 2147448388
  • 929 + 2147447459 = 2147448388

Showing the first eight; more decompositions exist.
