Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572646, here are decompositions:

17 + 33572629 = 33572646
89 + 33572557 = 33572646
109 + 33572537 = 33572646
113 + 33572533 = 33572646
157 + 33572489 = 33572646
199 + 33572447 = 33572646
229 + 33572417 = 33572646
269 + 33572377 = 33572646

Showing the first eight; more decompositions exist.
