Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472180, here are decompositions:

17 + 33472163 = 33472180
41 + 33472139 = 33472180
101 + 33472079 = 33472180
113 + 33472067 = 33472180
173 + 33472007 = 33472180
191 + 33471989 = 33472180
227 + 33471953 = 33472180
233 + 33471947 = 33472180

Showing the first eight; more decompositions exist.
