Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723330, here are decompositions:

13 + 8723317 = 8723330
19 + 8723311 = 8723330
127 + 8723203 = 8723330
139 + 8723191 = 8723330
181 + 8723149 = 8723330
193 + 8723137 = 8723330
223 + 8723107 = 8723330
241 + 8723089 = 8723330

Showing the first eight; more decompositions exist.
