Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723004, here are decompositions:

5 + 8722999 = 8723004
11 + 8722993 = 8723004
13 + 8722991 = 8723004
23 + 8722981 = 8723004
113 + 8722891 = 8723004
127 + 8722877 = 8723004
163 + 8722841 = 8723004
293 + 8722711 = 8723004

Showing the first eight; more decompositions exist.
