Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494246, here are decompositions:

5 + 31494241 = 31494246
67 + 31494179 = 31494246
89 + 31494157 = 31494246
103 + 31494143 = 31494246
127 + 31494119 = 31494246
149 + 31494097 = 31494246
163 + 31494083 = 31494246
167 + 31494079 = 31494246

Showing the first eight; more decompositions exist.
