Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518238, here are decompositions:

29 + 33518209 = 33518238
97 + 33518141 = 33518238
101 + 33518137 = 33518238
107 + 33518131 = 33518238
157 + 33518081 = 33518238
191 + 33518047 = 33518238
227 + 33518011 = 33518238
251 + 33517987 = 33518238

Showing the first eight; more decompositions exist.
