Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723286, here are decompositions:

43 + 8723243 = 8723286
73 + 8723213 = 8723286
83 + 8723203 = 8723286
137 + 8723149 = 8723286
149 + 8723137 = 8723286
163 + 8723123 = 8723286
179 + 8723107 = 8723286
197 + 8723089 = 8723286

Showing the first eight; more decompositions exist.
