Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533396, here are decompositions:

7 + 31533389 = 31533396
17 + 31533379 = 31533396
53 + 31533343 = 31533396
127 + 31533269 = 31533396
137 + 31533259 = 31533396
229 + 31533167 = 31533396
263 + 31533133 = 31533396
269 + 31533127 = 31533396

Showing the first eight; more decompositions exist.
