Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723040, here are decompositions:

23 + 8723017 = 8723040
41 + 8722999 = 8723040
47 + 8722993 = 8723040
59 + 8722981 = 8723040
71 + 8722969 = 8723040
127 + 8722913 = 8723040
149 + 8722891 = 8723040
163 + 8722877 = 8723040

Showing the first eight; more decompositions exist.
