Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543362, here are decompositions:

13 + 31543349 = 31543362
31 + 31543331 = 31543362
61 + 31543301 = 31543362
89 + 31543273 = 31543362
131 + 31543231 = 31543362
139 + 31543223 = 31543362
181 + 31543181 = 31543362
199 + 31543163 = 31543362

Showing the first eight; more decompositions exist.
