Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523814, here are decompositions:

11 + 31523803 = 31523814
13 + 31523801 = 31523814
53 + 31523761 = 31523814
61 + 31523753 = 31523814
107 + 31523707 = 31523814
163 + 31523651 = 31523814
167 + 31523647 = 31523814
181 + 31523633 = 31523814

Showing the first eight; more decompositions exist.
