Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621738, here are decompositions:

11 + 33621727 = 33621738
47 + 33621691 = 33621738
89 + 33621649 = 33621738
109 + 33621629 = 33621738
127 + 33621611 = 33621738
179 + 33621559 = 33621738
197 + 33621541 = 33621738
331 + 33621407 = 33621738

Showing the first eight; more decompositions exist.
