Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723260, here are decompositions:

17 + 8723243 = 8723260
47 + 8723213 = 8723260
137 + 8723123 = 8723260
179 + 8723081 = 8723260
197 + 8723063 = 8723260
269 + 8722991 = 8723260
311 + 8722949 = 8723260
347 + 8722913 = 8723260

Showing the first eight; more decompositions exist.
