Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723676, here are decompositions:

23 + 8723653 = 8723676
37 + 8723639 = 8723676
67 + 8723609 = 8723676
83 + 8723593 = 8723676
107 + 8723569 = 8723676
179 + 8723497 = 8723676
193 + 8723483 = 8723676
197 + 8723479 = 8723676

Showing the first eight; more decompositions exist.
