Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505218, here are decompositions:

7 + 33505211 = 33505218
31 + 33505187 = 33505218
41 + 33505177 = 33505218
101 + 33505117 = 33505218
151 + 33505067 = 33505218
167 + 33505051 = 33505218
179 + 33505039 = 33505218
211 + 33505007 = 33505218

Showing the first eight; more decompositions exist.
