Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620778, here are decompositions:

11 + 33620767 = 33620778
17 + 33620761 = 33620778
29 + 33620749 = 33620778
71 + 33620707 = 33620778
89 + 33620689 = 33620778
97 + 33620681 = 33620778
151 + 33620627 = 33620778
157 + 33620621 = 33620778

Showing the first eight; more decompositions exist.
