Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524202, here are decompositions:

5 + 31524197 = 31524202
41 + 31524161 = 31524202
179 + 31524023 = 31524202
191 + 31524011 = 31524202
263 + 31523939 = 31524202
401 + 31523801 = 31524202
449 + 31523753 = 31524202
569 + 31523633 = 31524202

Showing the first eight; more decompositions exist.
