Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553224, here are decompositions:

5 + 31553219 = 31553224
11 + 31553213 = 31553224
23 + 31553201 = 31553224
41 + 31553183 = 31553224
47 + 31553177 = 31553224
281 + 31552943 = 31553224
317 + 31552907 = 31553224
491 + 31552733 = 31553224

Showing the first eight; more decompositions exist.
