Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723300, here are decompositions:

97 + 8723203 = 8723300
109 + 8723191 = 8723300
151 + 8723149 = 8723300
163 + 8723137 = 8723300
193 + 8723107 = 8723300
211 + 8723089 = 8723300
283 + 8723017 = 8723300
307 + 8722993 = 8723300

Showing the first eight; more decompositions exist.
