Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621686, here are decompositions:

13 + 33621673 = 33621686
37 + 33621649 = 33621686
127 + 33621559 = 33621686
277 + 33621409 = 33621686
433 + 33621253 = 33621686
523 + 33621163 = 33621686
577 + 33621109 = 33621686
619 + 33621067 = 33621686

Showing the first eight; more decompositions exist.
