Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723078, here are decompositions:

31 + 8723047 = 8723078
37 + 8723041 = 8723078
61 + 8723017 = 8723078
79 + 8722999 = 8723078
97 + 8722981 = 8723078
109 + 8722969 = 8723078
367 + 8722711 = 8723078
457 + 8722621 = 8723078

Showing the first eight; more decompositions exist.
