Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523086, here are decompositions:

5 + 31523081 = 31523086
59 + 31523027 = 31523086
83 + 31523003 = 31523086
107 + 31522979 = 31523086
149 + 31522937 = 31523086
197 + 31522889 = 31523086
239 + 31522847 = 31523086
263 + 31522823 = 31523086

Showing the first eight; more decompositions exist.
