Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31298, here are decompositions:

31 + 31267 = 31298
61 + 31237 = 31298
67 + 31231 = 31298
79 + 31219 = 31298
109 + 31189 = 31298
139 + 31159 = 31298
151 + 31147 = 31298
229 + 31069 = 31298

Showing the first eight; more decompositions exist.
