Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404718, here are decompositions:

  • 7 + 2147404711 = 2147404718
  • 79 + 2147404639 = 2147404718
  • 97 + 2147404621 = 2147404718
  • 139 + 2147404579 = 2147404718
  • 229 + 2147404489 = 2147404718
  • 271 + 2147404447 = 2147404718
  • 337 + 2147404381 = 2147404718
  • 409 + 2147404309 = 2147404718

Showing the first eight; more decompositions exist.
