Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 384, here are decompositions:

  • 5 + 379 = 384
  • 11 + 373 = 384
  • 17 + 367 = 384
  • 31 + 353 = 384
  • 37 + 347 = 384
  • 47 + 337 = 384
  • 53 + 331 = 384
  • 67 + 317 = 384

Showing the first eight; more decompositions exist.
