Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618978, here are decompositions:

7 + 33618971 = 33618978
59 + 33618919 = 33618978
89 + 33618889 = 33618978
139 + 33618839 = 33618978
199 + 33618779 = 33618978
227 + 33618751 = 33618978
229 + 33618749 = 33618978
241 + 33618737 = 33618978

Showing the first eight; more decompositions exist.
