Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514672, here are decompositions:

19 + 31514653 = 31514672
31 + 31514641 = 31514672
43 + 31514629 = 31514672
73 + 31514599 = 31514672
139 + 31514533 = 31514672
193 + 31514479 = 31514672
199 + 31514473 = 31514672
223 + 31514449 = 31514672

Showing the first eight; more decompositions exist.
