Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621428, here are decompositions:

19 + 33621409 = 33621428
31 + 33621397 = 33621428
67 + 33621361 = 33621428
397 + 33621031 = 33621428
499 + 33620929 = 33621428
571 + 33620857 = 33621428
619 + 33620809 = 33621428
661 + 33620767 = 33621428

Showing the first eight; more decompositions exist.
