Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463232, here are decompositions:

5 + 31463227 = 31463232
19 + 31463213 = 31463232
29 + 31463203 = 31463232
71 + 31463161 = 31463232
109 + 31463123 = 31463232
149 + 31463083 = 31463232
263 + 31462969 = 31463232
331 + 31462901 = 31463232

Showing the first eight; more decompositions exist.
