Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618988, here are decompositions:

17 + 33618971 = 33618988
101 + 33618887 = 33618988
131 + 33618857 = 33618988
149 + 33618839 = 33618988
239 + 33618749 = 33618988
251 + 33618737 = 33618988
269 + 33618719 = 33618988
317 + 33618671 = 33618988

Showing the first eight; more decompositions exist.
