Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572268, here are decompositions:

17 + 33572251 = 33572268
31 + 33572237 = 33572268
127 + 33572141 = 33572268
137 + 33572131 = 33572268
151 + 33572117 = 33572268
227 + 33572041 = 33572268
239 + 33572029 = 33572268
241 + 33572027 = 33572268

Showing the first eight; more decompositions exist.
