Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514852, here are decompositions:

3 + 31514849 = 31514852
13 + 31514839 = 31514852
163 + 31514689 = 31514852
181 + 31514671 = 31514852
199 + 31514653 = 31514852
211 + 31514641 = 31514852
223 + 31514629 = 31514852
373 + 31514479 = 31514852

Showing the first eight; more decompositions exist.
