Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475414, here are decompositions:

7 + 31475407 = 31475414
13 + 31475401 = 31475414
43 + 31475371 = 31475414
73 + 31475341 = 31475414
97 + 31475317 = 31475414
127 + 31475287 = 31475414
163 + 31475251 = 31475414
283 + 31475131 = 31475414

Showing the first eight; more decompositions exist.
