Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517344, here are decompositions:

71 + 31517273 = 31517344
101 + 31517243 = 31517344
113 + 31517231 = 31517344
137 + 31517207 = 31517344
281 + 31517063 = 31517344
317 + 31517027 = 31517344
503 + 31516841 = 31517344
557 + 31516787 = 31517344

Showing the first eight; more decompositions exist.
