Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563096, here are decompositions:

7 + 31563089 = 31563096
23 + 31563073 = 31563096
53 + 31563043 = 31563096
67 + 31563029 = 31563096
83 + 31563013 = 31563096
109 + 31562987 = 31563096
113 + 31562983 = 31563096
137 + 31562959 = 31563096

Showing the first eight; more decompositions exist.
