Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475476, here are decompositions:

5 + 31475471 = 31475476
17 + 31475459 = 31475476
23 + 31475453 = 31475476
47 + 31475429 = 31475476
83 + 31475393 = 31475476
89 + 31475387 = 31475476
233 + 31475243 = 31475476
317 + 31475159 = 31475476

Showing the first eight; more decompositions exist.
