Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523298, here are decompositions:

5 + 31523293 = 31523298
19 + 31523279 = 31523298
31 + 31523267 = 31523298
47 + 31523251 = 31523298
61 + 31523237 = 31523298
67 + 31523231 = 31523298
71 + 31523227 = 31523298
89 + 31523209 = 31523298

Showing the first eight; more decompositions exist.
