Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531476, here are decompositions:

5 + 31531471 = 31531476
19 + 31531457 = 31531476
23 + 31531453 = 31531476
59 + 31531417 = 31531476
73 + 31531403 = 31531476
107 + 31531369 = 31531476
173 + 31531303 = 31531476
227 + 31531249 = 31531476

Showing the first eight; more decompositions exist.
