Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611988, here are decompositions:

29 + 33611959 = 33611988
37 + 33611951 = 33611988
61 + 33611927 = 33611988
131 + 33611857 = 33611988
167 + 33611821 = 33611988
181 + 33611807 = 33611988
191 + 33611797 = 33611988
197 + 33611791 = 33611988

Showing the first eight; more decompositions exist.
