Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463172, here are decompositions:

5 + 31463167 = 31463172
11 + 31463161 = 31463172
73 + 31463099 = 31463172
89 + 31463083 = 31463172
109 + 31463063 = 31463172
149 + 31463023 = 31463172
193 + 31462979 = 31463172
239 + 31462933 = 31463172

Showing the first eight; more decompositions exist.
