Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723358, here are decompositions:

5 + 8723353 = 8723358
11 + 8723347 = 8723358
37 + 8723321 = 8723358
41 + 8723317 = 8723358
47 + 8723311 = 8723358
167 + 8723191 = 8723358
251 + 8723107 = 8723358
269 + 8723089 = 8723358

Showing the first eight; more decompositions exist.
