Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523008, here are decompositions:

5 + 31523003 = 31523008
29 + 31522979 = 31523008
47 + 31522961 = 31523008
71 + 31522937 = 31523008
107 + 31522901 = 31523008
467 + 31522541 = 31523008
479 + 31522529 = 31523008
557 + 31522451 = 31523008

Showing the first eight; more decompositions exist.
