Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621314, here are decompositions:

47 + 31621267 = 31621314
97 + 31621217 = 31621314
157 + 31621157 = 31621314
163 + 31621151 = 31621314
173 + 31621141 = 31621314
181 + 31621133 = 31621314
191 + 31621123 = 31621314
233 + 31621081 = 31621314

Showing the first eight; more decompositions exist.
