Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620772, here are decompositions:

5 + 33620767 = 33620772
11 + 33620761 = 33620772
23 + 33620749 = 33620772
83 + 33620689 = 33620772
113 + 33620659 = 33620772
149 + 33620623 = 33620772
151 + 33620621 = 33620772
179 + 33620593 = 33620772

Showing the first eight; more decompositions exist.
