Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563276, here are decompositions:

7 + 31563269 = 31563276
23 + 31563253 = 31563276
67 + 31563209 = 31563276
83 + 31563193 = 31563276
89 + 31563187 = 31563276
113 + 31563163 = 31563276
127 + 31563149 = 31563276
139 + 31563137 = 31563276

Showing the first eight; more decompositions exist.
