Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532298, here are decompositions:

19 + 31532279 = 31532298
29 + 31532269 = 31532298
37 + 31532261 = 31532298
71 + 31532227 = 31532298
79 + 31532219 = 31532298
89 + 31532209 = 31532298
131 + 31532167 = 31532298
157 + 31532141 = 31532298

Showing the first eight; more decompositions exist.
