Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563298, here are decompositions:

29 + 31563269 = 31563298
89 + 31563209 = 31563298
149 + 31563149 = 31563298
167 + 31563131 = 31563298
257 + 31563041 = 31563298
269 + 31563029 = 31563298
311 + 31562987 = 31563298
317 + 31562981 = 31563298

Showing the first eight; more decompositions exist.
