Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463270, here are decompositions:

43 + 31463227 = 31463270
67 + 31463203 = 31463270
73 + 31463197 = 31463270
103 + 31463167 = 31463270
109 + 31463161 = 31463270
193 + 31463077 = 31463270
337 + 31462933 = 31463270
373 + 31462897 = 31463270

Showing the first eight; more decompositions exist.
