Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489372, here are decompositions:

11 + 33489361 = 33489372
23 + 33489349 = 33489372
31 + 33489341 = 33489372
53 + 33489319 = 33489372
79 + 33489293 = 33489372
89 + 33489283 = 33489372
131 + 33489241 = 33489372
149 + 33489223 = 33489372

Showing the first eight; more decompositions exist.
