Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489378, here are decompositions:

17 + 33489361 = 33489378
29 + 33489349 = 33489378
37 + 33489341 = 33489378
59 + 33489319 = 33489378
137 + 33489241 = 33489378
151 + 33489227 = 33489378
157 + 33489221 = 33489378
199 + 33489179 = 33489378

Showing the first eight; more decompositions exist.
