Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621530, here are decompositions:

277 + 33621253 = 33621530
367 + 33621163 = 33621530
421 + 33621109 = 33621530
463 + 33621067 = 33621530
499 + 33621031 = 33621530
571 + 33620959 = 33621530
601 + 33620929 = 33621530
619 + 33620911 = 33621530

Showing the first eight; more decompositions exist.
