Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621078, here are decompositions:

11 + 33621067 = 33621078
31 + 33621047 = 33621078
41 + 33621037 = 33621078
47 + 33621031 = 33621078
79 + 33620999 = 33621078
149 + 33620929 = 33621078
151 + 33620927 = 33621078
167 + 33620911 = 33621078

Showing the first eight; more decompositions exist.
