Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553326, here are decompositions:

5 + 31553321 = 31553326
47 + 31553279 = 31553326
53 + 31553273 = 31553326
107 + 31553219 = 31553326
113 + 31553213 = 31553326
149 + 31553177 = 31553326
257 + 31553069 = 31553326
263 + 31553063 = 31553326

Showing the first eight; more decompositions exist.
