Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723064, here are decompositions:

11 + 8723053 = 8723064
17 + 8723047 = 8723064
23 + 8723041 = 8723064
47 + 8723017 = 8723064
71 + 8722993 = 8723064
73 + 8722991 = 8723064
83 + 8722981 = 8723064
151 + 8722913 = 8723064

Showing the first eight; more decompositions exist.
