Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531362, here are decompositions:

59 + 31531303 = 31531362
61 + 31531301 = 31531362
89 + 31531273 = 31531362
101 + 31531261 = 31531362
113 + 31531249 = 31531362
199 + 31531163 = 31531362
223 + 31531139 = 31531362
263 + 31531099 = 31531362

Showing the first eight; more decompositions exist.
