Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738398, here are decompositions:

  • 47 + 8738351 = 8738398
  • 59 + 8738339 = 8738398
  • 167 + 8738231 = 8738398
  • 197 + 8738201 = 8738398
  • 269 + 8738129 = 8738398
  • 311 + 8738087 = 8738398
  • 419 + 8737979 = 8738398
  • 569 + 8737829 = 8738398

Showing the first eight; more decompositions exist.
