Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563434, here are decompositions:

3 + 31563431 = 31563434
31 + 31563403 = 31563434
43 + 31563391 = 31563434
151 + 31563283 = 31563434
157 + 31563277 = 31563434
181 + 31563253 = 31563434
241 + 31563193 = 31563434
271 + 31563163 = 31563434

Showing the first eight; more decompositions exist.
