Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723008, here are decompositions:

17 + 8722991 = 8723008
59 + 8722949 = 8723008
131 + 8722877 = 8723008
149 + 8722859 = 8723008
167 + 8722841 = 8723008
179 + 8722829 = 8723008
251 + 8722757 = 8723008
269 + 8722739 = 8723008

Showing the first eight; more decompositions exist.
