Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475454, here are decompositions:

11 + 31475443 = 31475454
47 + 31475407 = 31475454
53 + 31475401 = 31475454
61 + 31475393 = 31475454
67 + 31475387 = 31475454
83 + 31475371 = 31475454
113 + 31475341 = 31475454
137 + 31475317 = 31475454

Showing the first eight; more decompositions exist.
