Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463216, here are decompositions:

3 + 31463213 = 31463216
13 + 31463203 = 31463216
19 + 31463197 = 31463216
79 + 31463137 = 31463216
139 + 31463077 = 31463216
193 + 31463023 = 31463216
283 + 31462933 = 31463216
307 + 31462909 = 31463216

Showing the first eight; more decompositions exist.
