Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634978, here are decompositions:

7 + 8634971 = 8634978
17 + 8634961 = 8634978
31 + 8634947 = 8634978
61 + 8634917 = 8634978
71 + 8634907 = 8634978
89 + 8634889 = 8634978
97 + 8634881 = 8634978
127 + 8634851 = 8634978

Showing the first eight; more decompositions exist.
