Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482196, here are decompositions:

17 + 31482179 = 31482196
23 + 31482173 = 31482196
29 + 31482167 = 31482196
107 + 31482089 = 31482196
113 + 31482083 = 31482196
149 + 31482047 = 31482196
257 + 31481939 = 31482196
353 + 31481843 = 31482196

Showing the first eight; more decompositions exist.
