Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621178, here are decompositions:

5 + 33621173 = 33621178
29 + 33621149 = 33621178
131 + 33621047 = 33621178
179 + 33620999 = 33621178
251 + 33620927 = 33621178
359 + 33620819 = 33621178
389 + 33620789 = 33621178
557 + 33620621 = 33621178

Showing the first eight; more decompositions exist.
