Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517298, here are decompositions:

31 + 31517267 = 31517298
67 + 31517231 = 31517298
101 + 31517197 = 31517298
149 + 31517149 = 31517298
271 + 31517027 = 31517298
277 + 31517021 = 31517298
317 + 31516981 = 31517298
347 + 31516951 = 31517298

Showing the first eight; more decompositions exist.
