Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482508, here are decompositions:

107 + 31482401 = 31482508
227 + 31482281 = 31482508
251 + 31482257 = 31482508
389 + 31482119 = 31482508
419 + 31482089 = 31482508
461 + 31482047 = 31482508
467 + 31482041 = 31482508
557 + 31481951 = 31482508

Showing the first eight; more decompositions exist.
