Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724000, here are decompositions:

7 + 8723993 = 8724000
13 + 8723987 = 8724000
23 + 8723977 = 8724000
53 + 8723947 = 8724000
67 + 8723933 = 8724000
71 + 8723929 = 8724000
79 + 8723921 = 8724000
97 + 8723903 = 8724000

Showing the first eight; more decompositions exist.
