Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724006, here are decompositions:

13 + 8723993 = 8724006
19 + 8723987 = 8724006
29 + 8723977 = 8724006
59 + 8723947 = 8724006
73 + 8723933 = 8724006
97 + 8723909 = 8724006
103 + 8723903 = 8724006
107 + 8723899 = 8724006

Showing the first eight; more decompositions exist.
