Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724298, here are decompositions:

5 + 8724293 = 8724298
29 + 8724269 = 8724298
137 + 8724161 = 8724298
197 + 8724101 = 8724298
227 + 8724071 = 8724298
311 + 8723987 = 8724298
347 + 8723951 = 8724298
389 + 8723909 = 8724298

Showing the first eight; more decompositions exist.
