Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621912, here are decompositions:

11 + 33621901 = 33621912
31 + 33621881 = 33621912
53 + 33621859 = 33621912
73 + 33621839 = 33621912
89 + 33621823 = 33621912
131 + 33621781 = 33621912
151 + 33621761 = 33621912
199 + 33621713 = 33621912

Showing the first eight; more decompositions exist.
