Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617298, here are decompositions:

5 + 31617293 = 31617298
17 + 31617281 = 31617298
29 + 31617269 = 31617298
47 + 31617251 = 31617298
59 + 31617239 = 31617298
131 + 31617167 = 31617298
149 + 31617149 = 31617298
197 + 31617101 = 31617298

Showing the first eight; more decompositions exist.
