Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623440, here are decompositions:

  • 47 + 33623393 = 33623440
  • 83 + 33623357 = 33623440
  • 89 + 33623351 = 33623440
  • 113 + 33623327 = 33623440
  • 197 + 33623243 = 33623440
  • 239 + 33623201 = 33623440
  • 281 + 33623159 = 33623440
  • 311 + 33623129 = 33623440

Showing the first eight; more decompositions exist.
