Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621536, here are decompositions:

127 + 33621409 = 33621536
139 + 33621397 = 33621536
283 + 33621253 = 33621536
367 + 33621169 = 33621536
373 + 33621163 = 33621536
499 + 33621037 = 33621536
577 + 33620959 = 33621536
607 + 33620929 = 33621536

Showing the first eight; more decompositions exist.
