Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577220, here are decompositions:

13 + 33577207 = 33577220
37 + 33577183 = 33577220
43 + 33577177 = 33577220
109 + 33577111 = 33577220
181 + 33577039 = 33577220
199 + 33577021 = 33577220
223 + 33576997 = 33577220
277 + 33576943 = 33577220

Showing the first eight; more decompositions exist.
