Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490518, here are decompositions:

41 + 33490477 = 33490518
109 + 33490409 = 33490518
137 + 33490381 = 33490518
157 + 33490361 = 33490518
167 + 33490351 = 33490518
181 + 33490337 = 33490518
197 + 33490321 = 33490518
239 + 33490279 = 33490518

Showing the first eight; more decompositions exist.
