Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572688, here are decompositions:

5 + 33572683 = 33572688
41 + 33572647 = 33572688
59 + 33572629 = 33572688
131 + 33572557 = 33572688
151 + 33572537 = 33572688
167 + 33572521 = 33572688
199 + 33572489 = 33572688
241 + 33572447 = 33572688

Showing the first eight; more decompositions exist.
