Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543410, here are decompositions:

13 + 31543397 = 31543410
61 + 31543349 = 31543410
79 + 31543331 = 31543410
109 + 31543301 = 31543410
137 + 31543273 = 31543410
167 + 31543243 = 31543410
179 + 31543231 = 31543410
191 + 31543219 = 31543410

Showing the first eight; more decompositions exist.
