Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482246, here are decompositions:

17 + 31482229 = 31482246
67 + 31482179 = 31482246
73 + 31482173 = 31482246
79 + 31482167 = 31482246
127 + 31482119 = 31482246
149 + 31482097 = 31482246
157 + 31482089 = 31482246
163 + 31482083 = 31482246

Showing the first eight; more decompositions exist.
