Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723028, here are decompositions:

11 + 8723017 = 8723028
29 + 8722999 = 8723028
37 + 8722991 = 8723028
47 + 8722981 = 8723028
59 + 8722969 = 8723028
79 + 8722949 = 8723028
137 + 8722891 = 8723028
151 + 8722877 = 8723028

Showing the first eight; more decompositions exist.
