Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463220, here are decompositions:

7 + 31463213 = 31463220
17 + 31463203 = 31463220
23 + 31463197 = 31463220
53 + 31463167 = 31463220
59 + 31463161 = 31463220
73 + 31463147 = 31463220
83 + 31463137 = 31463220
97 + 31463123 = 31463220

Showing the first eight; more decompositions exist.
