Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530988, here are decompositions:

11 + 33530977 = 33530988
17 + 33530971 = 33530988
19 + 33530969 = 33530988
89 + 33530899 = 33530988
131 + 33530857 = 33530988
151 + 33530837 = 33530988
199 + 33530789 = 33530988
229 + 33530759 = 33530988

Showing the first eight; more decompositions exist.
