Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620972, here are decompositions:

13 + 33620959 = 33620972
43 + 33620929 = 33620972
61 + 33620911 = 33620972
163 + 33620809 = 33620972
211 + 33620761 = 33620972
223 + 33620749 = 33620972
283 + 33620689 = 33620972
313 + 33620659 = 33620972

Showing the first eight; more decompositions exist.
