Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473400, here are decompositions:

3 + 31473397 = 31473400
41 + 31473359 = 31473400
137 + 31473263 = 31473400
149 + 31473251 = 31473400
191 + 31473209 = 31473400
197 + 31473203 = 31473400
227 + 31473173 = 31473400
239 + 31473161 = 31473400

Showing the first eight; more decompositions exist.
