Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523010, here are decompositions:

7 + 31523003 = 31523010
23 + 31522987 = 31523010
31 + 31522979 = 31523010
59 + 31522951 = 31523010
73 + 31522937 = 31523010
109 + 31522901 = 31523010
137 + 31522873 = 31523010
163 + 31522847 = 31523010

Showing the first eight; more decompositions exist.
