Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472218, here are decompositions:

11 + 33472207 = 33472218
37 + 33472181 = 33472218
71 + 33472147 = 33472218
79 + 33472139 = 33472218
107 + 33472111 = 33472218
139 + 33472079 = 33472218
151 + 33472067 = 33472218
211 + 33472007 = 33472218

Showing the first eight; more decompositions exist.
