Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482170, here are decompositions:

3 + 31482167 = 31482170
67 + 31482103 = 31482170
73 + 31482097 = 31482170
103 + 31482067 = 31482170
127 + 31482043 = 31482170
157 + 31482013 = 31482170
271 + 31481899 = 31482170
283 + 31481887 = 31482170

Showing the first eight; more decompositions exist.
