Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723162, here are decompositions:

13 + 8723149 = 8723162
73 + 8723089 = 8723162
109 + 8723053 = 8723162
163 + 8722999 = 8723162
181 + 8722981 = 8723162
193 + 8722969 = 8723162
271 + 8722891 = 8723162
373 + 8722789 = 8723162

Showing the first eight; more decompositions exist.
