Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471934, here are decompositions:

103 + 31471831 = 31471934
223 + 31471711 = 31471934
271 + 31471663 = 31471934
313 + 31471621 = 31471934
523 + 31471411 = 31471934
547 + 31471387 = 31471934
577 + 31471357 = 31471934
727 + 31471207 = 31471934

Showing the first eight; more decompositions exist.
