Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508638, here are decompositions:

11 + 33508627 = 33508638
19 + 33508619 = 33508638
61 + 33508577 = 33508638
89 + 33508549 = 33508638
131 + 33508507 = 33508638
139 + 33508499 = 33508638
151 + 33508487 = 33508638
167 + 33508471 = 33508638

Showing the first eight; more decompositions exist.
