Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621072, here are decompositions:

5 + 33621067 = 33621072
41 + 33621031 = 33621072
73 + 33620999 = 33621072
113 + 33620959 = 33621072
181 + 33620891 = 33621072
263 + 33620809 = 33621072
269 + 33620803 = 33621072
283 + 33620789 = 33621072

Showing the first eight; more decompositions exist.
