Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621288, here are decompositions:

  • 5 + 33621283 = 33621288
  • 37 + 33621251 = 33621288
  • 139 + 33621149 = 33621288
  • 179 + 33621109 = 33621288
  • 241 + 33621047 = 33621288
  • 251 + 33621037 = 33621288
  • 257 + 33621031 = 33621288
  • 359 + 33620929 = 33621288

Showing the first eight; more decompositions exist.
