Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621156, here are decompositions:

7 + 33621149 = 33621156
43 + 33621113 = 33621156
47 + 33621109 = 33621156
73 + 33621083 = 33621156
89 + 33621067 = 33621156
109 + 33621047 = 33621156
157 + 33620999 = 33621156
197 + 33620959 = 33621156

Showing the first eight; more decompositions exist.
