Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621572, here are decompositions:

13 + 33621559 = 33621572
31 + 33621541 = 33621572
163 + 33621409 = 33621572
211 + 33621361 = 33621572
409 + 33621163 = 33621572
463 + 33621109 = 33621572
541 + 33621031 = 33621572
613 + 33620959 = 33621572

Showing the first eight; more decompositions exist.
