Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472158, here are decompositions:

11 + 33472147 = 33472158
17 + 33472141 = 33472158
19 + 33472139 = 33472158
47 + 33472111 = 33472158
79 + 33472079 = 33472158
149 + 33472009 = 33472158
151 + 33472007 = 33472158
179 + 33471979 = 33472158

Showing the first eight; more decompositions exist.
