Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553268, here are decompositions:

7 + 31553261 = 31553268
67 + 31553201 = 31553268
107 + 31553161 = 31553268
179 + 31553089 = 31553268
191 + 31553077 = 31553268
199 + 31553069 = 31553268
251 + 31553017 = 31553268
269 + 31552999 = 31553268

Showing the first eight; more decompositions exist.
