Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620988, here are decompositions:

29 + 33620959 = 33620988
59 + 33620929 = 33620988
61 + 33620927 = 33620988
97 + 33620891 = 33620988
131 + 33620857 = 33620988
179 + 33620809 = 33620988
199 + 33620789 = 33620988
227 + 33620761 = 33620988

Showing the first eight; more decompositions exist.
