Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536298, here are decompositions:

5 + 31536293 = 31536298
11 + 31536287 = 31536298
71 + 31536227 = 31536298
137 + 31536161 = 31536298
197 + 31536101 = 31536298
281 + 31536017 = 31536298
317 + 31535981 = 31536298
359 + 31535939 = 31536298

Showing the first eight; more decompositions exist.
