Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494250, here are decompositions:

3 + 31494247 = 31494250
71 + 31494179 = 31494250
89 + 31494161 = 31494250
107 + 31494143 = 31494250
131 + 31494119 = 31494250
167 + 31494083 = 31494250
197 + 31494053 = 31494250
251 + 31493999 = 31494250

Showing the first eight; more decompositions exist.
