Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481218, here are decompositions:

31 + 33481187 = 33481218
59 + 33481159 = 33481218
101 + 33481117 = 33481218
131 + 33481087 = 33481218
137 + 33481081 = 33481218
151 + 33481067 = 33481218
181 + 33481037 = 33481218
191 + 33481027 = 33481218

Showing the first eight; more decompositions exist.
