Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533456, here are decompositions:

5 + 31533451 = 31533456
7 + 31533449 = 31533456
43 + 31533413 = 31533456
47 + 31533409 = 31533456
67 + 31533389 = 31533456
113 + 31533343 = 31533456
197 + 31533259 = 31533456
307 + 31533149 = 31533456

Showing the first eight; more decompositions exist.
