Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542968, here are decompositions:

19 + 31542949 = 31542968
31 + 31542937 = 31542968
139 + 31542829 = 31542968
157 + 31542811 = 31542968
181 + 31542787 = 31542968
241 + 31542727 = 31542968
271 + 31542697 = 31542968
337 + 31542631 = 31542968

Showing the first eight; more decompositions exist.
