Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723010, here are decompositions:

11 + 8722999 = 8723010
17 + 8722993 = 8723010
19 + 8722991 = 8723010
29 + 8722981 = 8723010
41 + 8722969 = 8723010
61 + 8722949 = 8723010
97 + 8722913 = 8723010
151 + 8722859 = 8723010

Showing the first eight; more decompositions exist.
