Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483090, here are decompositions:

3 + 31483087 = 31483090
29 + 31483061 = 31483090
113 + 31482977 = 31483090
251 + 31482839 = 31483090
257 + 31482833 = 31483090
269 + 31482821 = 31483090
311 + 31482779 = 31483090
347 + 31482743 = 31483090

Showing the first eight; more decompositions exist.
