Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455324, here are decompositions:

11 + 31455313 = 31455324
23 + 31455301 = 31455324
31 + 31455293 = 31455324
53 + 31455271 = 31455324
101 + 31455223 = 31455324
127 + 31455197 = 31455324
163 + 31455161 = 31455324
193 + 31455131 = 31455324

Showing the first eight; more decompositions exist.
