Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543464, here are decompositions:

11 + 31543453 = 31543464
13 + 31543451 = 31543464
67 + 31543397 = 31543464
103 + 31543361 = 31543464
163 + 31543301 = 31543464
191 + 31543273 = 31543464
233 + 31543231 = 31543464
241 + 31543223 = 31543464

Showing the first eight; more decompositions exist.
