Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471476, here are decompositions:

7 + 31471469 = 31471476
19 + 31471457 = 31471476
37 + 31471439 = 31471476
79 + 31471397 = 31471476
89 + 31471387 = 31471476
103 + 31471373 = 31471476
263 + 31471213 = 31471476
269 + 31471207 = 31471476

Showing the first eight; more decompositions exist.
