Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620320, here are decompositions:

  • 17 + 33620303 = 33620320
  • 131 + 33620189 = 33620320
  • 137 + 33620183 = 33620320
  • 191 + 33620129 = 33620320
  • 263 + 33620057 = 33620320
  • 269 + 33620051 = 33620320
  • 281 + 33620039 = 33620320
  • 317 + 33620003 = 33620320

Showing the first eight; more decompositions exist.
