Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723152, here are decompositions:

3 + 8723149 = 8723152
29 + 8723123 = 8723152
71 + 8723081 = 8723152
89 + 8723063 = 8723152
239 + 8722913 = 8723152
293 + 8722859 = 8723152
311 + 8722841 = 8723152
353 + 8722799 = 8723152

Showing the first eight; more decompositions exist.
