Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531332, here are decompositions:

29 + 31531303 = 31531332
31 + 31531301 = 31531332
59 + 31531273 = 31531332
61 + 31531271 = 31531332
71 + 31531261 = 31531332
83 + 31531249 = 31531332
193 + 31531139 = 31531332
233 + 31531099 = 31531332

Showing the first eight; more decompositions exist.
