Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621842, here are decompositions:

3 + 33621839 = 33621842
19 + 33621823 = 33621842
61 + 33621781 = 33621842
151 + 33621691 = 33621842
181 + 33621661 = 33621842
193 + 33621649 = 33621842
283 + 33621559 = 33621842
433 + 33621409 = 33621842

Showing the first eight; more decompositions exist.
