Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483386, here are decompositions:

17 + 31483369 = 31483386
59 + 31483327 = 31483386
73 + 31483313 = 31483386
79 + 31483307 = 31483386
149 + 31483237 = 31483386
157 + 31483229 = 31483386
173 + 31483213 = 31483386
223 + 31483163 = 31483386

Showing the first eight; more decompositions exist.
