Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531308, here are decompositions:

5 + 31531303 = 31531308
7 + 31531301 = 31531308
37 + 31531271 = 31531308
41 + 31531267 = 31531308
47 + 31531261 = 31531308
59 + 31531249 = 31531308
191 + 31531117 = 31531308
229 + 31531079 = 31531308

Showing the first eight; more decompositions exist.
