Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515208, here are decompositions:

5 + 33515203 = 33515208
79 + 33515129 = 33515208
109 + 33515099 = 33515208
131 + 33515077 = 33515208
149 + 33515059 = 33515208
151 + 33515057 = 33515208
239 + 33514969 = 33515208
241 + 33514967 = 33515208

Showing the first eight; more decompositions exist.
