Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514152, here are decompositions:

3 + 31514149 = 31514152
71 + 31514081 = 31514152
359 + 31513793 = 31514152
431 + 31513721 = 31514152
443 + 31513709 = 31514152
491 + 31513661 = 31514152
821 + 31513331 = 31514152
1061 + 31513091 = 31514152

Showing the first eight; more decompositions exist.
