Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621516, here are decompositions:

43 + 33621473 = 33621516
79 + 33621437 = 33621516
107 + 33621409 = 33621516
109 + 33621407 = 33621516
127 + 33621389 = 33621516
233 + 33621283 = 33621516
263 + 33621253 = 33621516
283 + 33621233 = 33621516

Showing the first eight; more decompositions exist.
