Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518294, here are decompositions:

7 + 31518287 = 31518294
13 + 31518281 = 31518294
23 + 31518271 = 31518294
97 + 31518197 = 31518294
113 + 31518181 = 31518294
131 + 31518163 = 31518294
233 + 31518061 = 31518294
257 + 31518037 = 31518294

Showing the first eight; more decompositions exist.
