Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608320, here are decompositions:

  • 3 + 33608317 = 33608320
  • 47 + 33608273 = 33608320
  • 107 + 33608213 = 33608320
  • 149 + 33608171 = 33608320
  • 269 + 33608051 = 33608320
  • 281 + 33608039 = 33608320
  • 293 + 33608027 = 33608320
  • 353 + 33607967 = 33608320

Showing the first eight; more decompositions exist.
