Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620990, here are decompositions:

31 + 33620959 = 33620990
61 + 33620929 = 33620990
79 + 33620911 = 33620990
181 + 33620809 = 33620990
223 + 33620767 = 33620990
229 + 33620761 = 33620990
241 + 33620749 = 33620990
283 + 33620707 = 33620990

Showing the first eight; more decompositions exist.
