Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723066, here are decompositions:

3 + 8723063 = 8723066
13 + 8723053 = 8723066
19 + 8723047 = 8723066
67 + 8722999 = 8723066
73 + 8722993 = 8723066
97 + 8722969 = 8723066
277 + 8722789 = 8723066
463 + 8722603 = 8723066

Showing the first eight; more decompositions exist.
