Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556218, here are decompositions:

11 + 33556207 = 33556218
29 + 33556189 = 33556218
61 + 33556157 = 33556218
107 + 33556111 = 33556218
131 + 33556087 = 33556218
149 + 33556069 = 33556218
167 + 33556051 = 33556218
181 + 33556037 = 33556218

Showing the first eight; more decompositions exist.
