Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724288, here are decompositions:

5 + 8724283 = 8724288
19 + 8724269 = 8724288
29 + 8724259 = 8724288
47 + 8724241 = 8724288
107 + 8724181 = 8724288
127 + 8724161 = 8724288
149 + 8724139 = 8724288
311 + 8723977 = 8724288

Showing the first eight; more decompositions exist.
