Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518218, here are decompositions:

5 + 33518213 = 33518218
137 + 33518081 = 33518218
197 + 33518021 = 33518218
311 + 33517907 = 33518218
317 + 33517901 = 33518218
347 + 33517871 = 33518218
521 + 33517697 = 33518218
599 + 33517619 = 33518218

Showing the first eight; more decompositions exist.
