Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503172, here are decompositions:

11 + 33503161 = 33503172
83 + 33503089 = 33503172
89 + 33503083 = 33503172
103 + 33503069 = 33503172
113 + 33503059 = 33503172
151 + 33503021 = 33503172
163 + 33503009 = 33503172
173 + 33502999 = 33503172

Showing the first eight; more decompositions exist.
