Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482298, here are decompositions:

5 + 31482293 = 31482298
17 + 31482281 = 31482298
41 + 31482257 = 31482298
131 + 31482167 = 31482298
179 + 31482119 = 31482298
251 + 31482047 = 31482298
257 + 31482041 = 31482298
317 + 31481981 = 31482298

Showing the first eight; more decompositions exist.
