Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514774, here are decompositions:

3 + 31514771 = 31514774
43 + 31514731 = 31514774
103 + 31514671 = 31514774
223 + 31514551 = 31514774
241 + 31514533 = 31514774
373 + 31514401 = 31514774
631 + 31514143 = 31514774
661 + 31514113 = 31514774

Showing the first eight; more decompositions exist.
