Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514924, here are decompositions:

13 + 31514911 = 31514924
31 + 31514893 = 31514924
193 + 31514731 = 31514924
271 + 31514653 = 31514924
283 + 31514641 = 31514924
373 + 31514551 = 31514924
523 + 31514401 = 31514924
733 + 31514191 = 31514924

Showing the first eight; more decompositions exist.
