Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463298, here are decompositions:

17 + 31463281 = 31463298
29 + 31463269 = 31463298
37 + 31463261 = 31463298
71 + 31463227 = 31463298
101 + 31463197 = 31463298
131 + 31463167 = 31463298
137 + 31463161 = 31463298
151 + 31463147 = 31463298

Showing the first eight; more decompositions exist.
