Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514972, here are decompositions:

3 + 31514969 = 31514972
61 + 31514911 = 31514972
79 + 31514893 = 31514972
103 + 31514869 = 31514972
241 + 31514731 = 31514972
283 + 31514689 = 31514972
331 + 31514641 = 31514972
373 + 31514599 = 31514972

Showing the first eight; more decompositions exist.
