Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751008, here are decompositions:

61 + 8750947 = 8751008
67 + 8750941 = 8751008
127 + 8750881 = 8751008
151 + 8750857 = 8751008
199 + 8750809 = 8751008
271 + 8750737 = 8751008
307 + 8750701 = 8751008
367 + 8750641 = 8751008

Showing the first eight; more decompositions exist.
