Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514744, here are decompositions:

3 + 31514741 = 31514744
13 + 31514731 = 31514744
73 + 31514671 = 31514744
103 + 31514641 = 31514744
193 + 31514551 = 31514744
211 + 31514533 = 31514744
271 + 31514473 = 31514744
523 + 31514221 = 31514744

Showing the first eight; more decompositions exist.
