Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489390, here are decompositions:

13 + 33489377 = 33489390
29 + 33489361 = 33489390
41 + 33489349 = 33489390
71 + 33489319 = 33489390
97 + 33489293 = 33489390
107 + 33489283 = 33489390
149 + 33489241 = 33489390
163 + 33489227 = 33489390

Showing the first eight; more decompositions exist.
