Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530940, here are decompositions:

41 + 33530899 = 33530940
83 + 33530857 = 33530940
103 + 33530837 = 33530940
127 + 33530813 = 33530940
151 + 33530789 = 33530940
167 + 33530773 = 33530940
181 + 33530759 = 33530940
199 + 33530741 = 33530940

Showing the first eight; more decompositions exist.
