Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483006, here are decompositions:

3 + 31483003 = 31483006
29 + 31482977 = 31483006
59 + 31482947 = 31483006
167 + 31482839 = 31483006
173 + 31482833 = 31483006
227 + 31482779 = 31483006
263 + 31482743 = 31483006
389 + 31482617 = 31483006

Showing the first eight; more decompositions exist.
