Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563360, here are decompositions:

11 + 31563349 = 31563360
13 + 31563347 = 31563360
83 + 31563277 = 31563360
107 + 31563253 = 31563360
139 + 31563221 = 31563360
151 + 31563209 = 31563360
167 + 31563193 = 31563360
173 + 31563187 = 31563360

Showing the first eight; more decompositions exist.
