Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608728, here are decompositions:

5 + 33608723 = 33608728
11 + 33608717 = 33608728
89 + 33608639 = 33608728
149 + 33608579 = 33608728
317 + 33608411 = 33608728
359 + 33608369 = 33608728
557 + 33608171 = 33608728
677 + 33608051 = 33608728

Showing the first eight; more decompositions exist.
