Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517218, here are decompositions:

11 + 33517207 = 33517218
29 + 33517189 = 33517218
37 + 33517181 = 33517218
41 + 33517177 = 33517218
67 + 33517151 = 33517218
101 + 33517117 = 33517218
131 + 33517087 = 33517218
157 + 33517061 = 33517218

Showing the first eight; more decompositions exist.
