Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723322, here are decompositions:

5 + 8723317 = 8723322
11 + 8723311 = 8723322
19 + 8723303 = 8723322
79 + 8723243 = 8723322
109 + 8723213 = 8723322
131 + 8723191 = 8723322
173 + 8723149 = 8723322
199 + 8723123 = 8723322

Showing the first eight; more decompositions exist.
