Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627994, here are decompositions:

7 + 8627987 = 8627994
17 + 8627977 = 8627994
41 + 8627953 = 8627994
47 + 8627947 = 8627994
83 + 8627911 = 8627994
97 + 8627897 = 8627994
101 + 8627893 = 8627994
127 + 8627867 = 8627994

Showing the first eight; more decompositions exist.
