Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489988, here are decompositions:

11 + 33489977 = 33489988
41 + 33489947 = 33489988
47 + 33489941 = 33489988
131 + 33489857 = 33489988
149 + 33489839 = 33489988
197 + 33489791 = 33489988
251 + 33489737 = 33489988
281 + 33489707 = 33489988

Showing the first eight; more decompositions exist.
