Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621620, here are decompositions:

61 + 33621559 = 33621620
79 + 33621541 = 33621620
211 + 33621409 = 33621620
223 + 33621397 = 33621620
337 + 33621283 = 33621620
367 + 33621253 = 33621620
457 + 33621163 = 33621620
661 + 33620959 = 33621620

Showing the first eight; more decompositions exist.
