Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724234, here are decompositions:

11 + 8724223 = 8724234
53 + 8724181 = 8724234
73 + 8724161 = 8724234
107 + 8724127 = 8724234
163 + 8724071 = 8724234
241 + 8723993 = 8724234
257 + 8723977 = 8724234
283 + 8723951 = 8724234

Showing the first eight; more decompositions exist.
