Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621440, here are decompositions:

3 + 33621437 = 33621440
31 + 33621409 = 33621440
43 + 33621397 = 33621440
79 + 33621361 = 33621440
157 + 33621283 = 33621440
271 + 33621169 = 33621440
277 + 33621163 = 33621440
331 + 33621109 = 33621440

Showing the first eight; more decompositions exist.
