Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523916, here are decompositions:

113 + 31523803 = 31523916
163 + 31523753 = 31523916
167 + 31523749 = 31523916
257 + 31523659 = 31523916
269 + 31523647 = 31523916
283 + 31523633 = 31523916
317 + 31523599 = 31523916
337 + 31523579 = 31523916

Showing the first eight; more decompositions exist.
