Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572658, here are decompositions:

11 + 33572647 = 33572658
29 + 33572629 = 33572658
101 + 33572557 = 33572658
131 + 33572527 = 33572658
137 + 33572521 = 33572658
211 + 33572447 = 33572658
241 + 33572417 = 33572658
277 + 33572381 = 33572658

Showing the first eight; more decompositions exist.
