Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553298, here are decompositions:

19 + 31553279 = 31553298
37 + 31553261 = 31553298
79 + 31553219 = 31553298
97 + 31553201 = 31553298
137 + 31553161 = 31553298
229 + 31553069 = 31553298
277 + 31553021 = 31553298
281 + 31553017 = 31553298

Showing the first eight; more decompositions exist.
