Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518220, here are decompositions:

7 + 33518213 = 33518220
11 + 33518209 = 33518220
79 + 33518141 = 33518220
83 + 33518137 = 33518220
89 + 33518131 = 33518220
101 + 33518119 = 33518220
139 + 33518081 = 33518220
173 + 33518047 = 33518220

Showing the first eight; more decompositions exist.
