Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456932, here are decompositions:

5 + 31456927 = 31456932
29 + 31456903 = 31456932
41 + 31456891 = 31456932
83 + 31456849 = 31456932
103 + 31456829 = 31456932
113 + 31456819 = 31456932
151 + 31456781 = 31456932
163 + 31456769 = 31456932

Showing the first eight; more decompositions exist.
