Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543284, here are decompositions:

11 + 31543273 = 31543284
41 + 31543243 = 31543284
53 + 31543231 = 31543284
61 + 31543223 = 31543284
67 + 31543217 = 31543284
103 + 31543181 = 31543284
151 + 31543133 = 31543284
181 + 31543103 = 31543284

Showing the first eight; more decompositions exist.
