Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621040, here are decompositions:

3 + 33621037 = 33621040
41 + 33620999 = 33621040
113 + 33620927 = 33621040
149 + 33620891 = 33621040
227 + 33620813 = 33621040
251 + 33620789 = 33621040
359 + 33620681 = 33621040
419 + 33620621 = 33621040

Showing the first eight; more decompositions exist.
