Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723306, here are decompositions:

3 + 8723303 = 8723306
103 + 8723203 = 8723306
157 + 8723149 = 8723306
199 + 8723107 = 8723306
307 + 8722999 = 8723306
313 + 8722993 = 8723306
337 + 8722969 = 8723306
829 + 8722477 = 8723306

Showing the first eight; more decompositions exist.
