Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724016, here are decompositions:

3 + 8724013 = 8724016
23 + 8723993 = 8724016
29 + 8723987 = 8724016
83 + 8723933 = 8724016
107 + 8723909 = 8724016
113 + 8723903 = 8724016
137 + 8723879 = 8724016
227 + 8723789 = 8724016

Showing the first eight; more decompositions exist.
