Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524298, here are decompositions:

5 + 31524293 = 31524298
41 + 31524257 = 31524298
101 + 31524197 = 31524298
131 + 31524167 = 31524298
137 + 31524161 = 31524298
191 + 31524107 = 31524298
251 + 31524047 = 31524298
359 + 31523939 = 31524298

Showing the first eight; more decompositions exist.
