Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524358, here are decompositions:

101 + 31524257 = 31524358
191 + 31524167 = 31524358
197 + 31524161 = 31524358
251 + 31524107 = 31524358
311 + 31524047 = 31524358
347 + 31524011 = 31524358
419 + 31523939 = 31524358
557 + 31523801 = 31524358

Showing the first eight; more decompositions exist.
