Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563310, here are decompositions:

41 + 31563269 = 31563310
89 + 31563221 = 31563310
101 + 31563209 = 31563310
173 + 31563137 = 31563310
179 + 31563131 = 31563310
269 + 31563041 = 31563310
281 + 31563029 = 31563310
461 + 31562849 = 31563310

Showing the first eight; more decompositions exist.
