Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723660, here are decompositions:

7 + 8723653 = 8723660
67 + 8723593 = 8723660
109 + 8723551 = 8723660
139 + 8723521 = 8723660
163 + 8723497 = 8723660
181 + 8723479 = 8723660
223 + 8723437 = 8723660
241 + 8723419 = 8723660

Showing the first eight; more decompositions exist.
