Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723166, here are decompositions:

17 + 8723149 = 8723166
29 + 8723137 = 8723166
43 + 8723123 = 8723166
59 + 8723107 = 8723166
103 + 8723063 = 8723166
113 + 8723053 = 8723166
149 + 8723017 = 8723166
167 + 8722999 = 8723166

Showing the first eight; more decompositions exist.
