Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533536, here are decompositions:

3 + 31533533 = 31533536
19 + 31533517 = 31533536
37 + 31533499 = 31533536
127 + 31533409 = 31533536
157 + 31533379 = 31533536
193 + 31533343 = 31533536
277 + 31533259 = 31533536
409 + 31533127 = 31533536

Showing the first eight; more decompositions exist.
