Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475460, here are decompositions:

7 + 31475453 = 31475460
17 + 31475443 = 31475460
31 + 31475429 = 31475460
53 + 31475407 = 31475460
59 + 31475401 = 31475460
67 + 31475393 = 31475460
73 + 31475387 = 31475460
89 + 31475371 = 31475460

Showing the first eight; more decompositions exist.
