Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621338, here are decompositions:

229 + 33621109 = 33621338
271 + 33621067 = 33621338
307 + 33621031 = 33621338
379 + 33620959 = 33621338
409 + 33620929 = 33621338
571 + 33620767 = 33621338
577 + 33620761 = 33621338
631 + 33620707 = 33621338

Showing the first eight; more decompositions exist.
