Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493852, here are decompositions:

31 + 31493821 = 31493852
73 + 31493779 = 31493852
109 + 31493743 = 31493852
163 + 31493689 = 31493852
199 + 31493653 = 31493852
211 + 31493641 = 31493852
241 + 31493611 = 31493852
283 + 31493569 = 31493852

Showing the first eight; more decompositions exist.
