Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723208, here are decompositions:

5 + 8723203 = 8723208
17 + 8723191 = 8723208
59 + 8723149 = 8723208
71 + 8723137 = 8723208
101 + 8723107 = 8723208
127 + 8723081 = 8723208
167 + 8723041 = 8723208
191 + 8723017 = 8723208

Showing the first eight; more decompositions exist.
