Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620440, here are decompositions:

3 + 33620437 = 33620440
11 + 33620429 = 33620440
53 + 33620387 = 33620440
59 + 33620381 = 33620440
83 + 33620357 = 33620440
89 + 33620351 = 33620440
137 + 33620303 = 33620440
239 + 33620201 = 33620440

Showing the first eight; more decompositions exist.
