Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723288, here are decompositions:

97 + 8723191 = 8723288
139 + 8723149 = 8723288
151 + 8723137 = 8723288
181 + 8723107 = 8723288
199 + 8723089 = 8723288
241 + 8723047 = 8723288
271 + 8723017 = 8723288
307 + 8722981 = 8723288

Showing the first eight; more decompositions exist.
