Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508628, here are decompositions:

79 + 33508549 = 33508628
157 + 33508471 = 33508628
211 + 33508417 = 33508628
337 + 33508291 = 33508628
367 + 33508261 = 33508628
409 + 33508219 = 33508628
691 + 33507937 = 33508628
739 + 33507889 = 33508628

Showing the first eight; more decompositions exist.
