Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723156, here are decompositions:

7 + 8723149 = 8723156
19 + 8723137 = 8723156
67 + 8723089 = 8723156
103 + 8723053 = 8723156
109 + 8723047 = 8723156
139 + 8723017 = 8723156
157 + 8722999 = 8723156
163 + 8722993 = 8723156

Showing the first eight; more decompositions exist.
