Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543416, here are decompositions:

19 + 31543397 = 31543416
67 + 31543349 = 31543416
173 + 31543243 = 31543416
193 + 31543223 = 31543416
197 + 31543219 = 31543416
199 + 31543217 = 31543416
283 + 31543133 = 31543416
313 + 31543103 = 31543416

Showing the first eight; more decompositions exist.
