Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723204, here are decompositions:

13 + 8723191 = 8723204
67 + 8723137 = 8723204
97 + 8723107 = 8723204
151 + 8723053 = 8723204
157 + 8723047 = 8723204
163 + 8723041 = 8723204
211 + 8722993 = 8723204
223 + 8722981 = 8723204

Showing the first eight; more decompositions exist.
