Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627904, here are decompositions:

7 + 8627897 = 8627904
11 + 8627893 = 8627904
37 + 8627867 = 8627904
53 + 8627851 = 8627904
71 + 8627833 = 8627904
97 + 8627807 = 8627904
127 + 8627777 = 8627904
163 + 8627741 = 8627904

Showing the first eight; more decompositions exist.
