Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475514, here are decompositions:

23 + 31475491 = 31475514
43 + 31475471 = 31475514
61 + 31475453 = 31475514
71 + 31475443 = 31475514
107 + 31475407 = 31475514
113 + 31475401 = 31475514
127 + 31475387 = 31475514
173 + 31475341 = 31475514

Showing the first eight; more decompositions exist.
