Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621560, here are decompositions:

19 + 33621541 = 33621560
151 + 33621409 = 33621560
163 + 33621397 = 33621560
199 + 33621361 = 33621560
277 + 33621283 = 33621560
307 + 33621253 = 33621560
397 + 33621163 = 33621560
523 + 33621037 = 33621560

Showing the first eight; more decompositions exist.
