Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518172, here are decompositions:

31 + 33518141 = 33518172
41 + 33518131 = 33518172
53 + 33518119 = 33518172
151 + 33518021 = 33518172
229 + 33517943 = 33518172
251 + 33517921 = 33518172
269 + 33517903 = 33518172
271 + 33517901 = 33518172

Showing the first eight; more decompositions exist.
