Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724004, here are decompositions:

11 + 8723993 = 8724004
17 + 8723987 = 8724004
53 + 8723951 = 8724004
71 + 8723933 = 8724004
83 + 8723921 = 8724004
101 + 8723903 = 8724004
197 + 8723807 = 8724004
521 + 8723483 = 8724004

Showing the first eight; more decompositions exist.
