Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483510, here are decompositions:

17 + 31483493 = 31483510
41 + 31483469 = 31483510
53 + 31483457 = 31483510
197 + 31483313 = 31483510
281 + 31483229 = 31483510
293 + 31483217 = 31483510
347 + 31483163 = 31483510
449 + 31483061 = 31483510

Showing the first eight; more decompositions exist.
