Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523364, here are decompositions:

17 + 31523347 = 31523364
71 + 31523293 = 31523364
97 + 31523267 = 31523364
113 + 31523251 = 31523364
127 + 31523237 = 31523364
137 + 31523227 = 31523364
157 + 31523207 = 31523364
163 + 31523201 = 31523364

Showing the first eight; more decompositions exist.
