Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563132, here are decompositions:

5 + 31563127 = 31563132
43 + 31563089 = 31563132
59 + 31563073 = 31563132
89 + 31563043 = 31563132
101 + 31563031 = 31563132
103 + 31563029 = 31563132
131 + 31563001 = 31563132
149 + 31562983 = 31563132

Showing the first eight; more decompositions exist.
