Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483316, here are decompositions:

3 + 31483313 = 31483316
79 + 31483237 = 31483316
103 + 31483213 = 31483316
199 + 31483117 = 31483316
223 + 31483093 = 31483316
229 + 31483087 = 31483316
313 + 31483003 = 31483316
409 + 31482907 = 31483316

Showing the first eight; more decompositions exist.
