Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621740, here are decompositions:

13 + 33621727 = 33621740
67 + 33621673 = 33621740
79 + 33621661 = 33621740
181 + 33621559 = 33621740
199 + 33621541 = 33621740
331 + 33621409 = 33621740
379 + 33621361 = 33621740
457 + 33621283 = 33621740

Showing the first eight; more decompositions exist.
