Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694978, here are decompositions:

7 + 8694971 = 8694978
11 + 8694967 = 8694978
31 + 8694947 = 8694978
37 + 8694941 = 8694978
79 + 8694899 = 8694978
109 + 8694869 = 8694978
137 + 8694841 = 8694978
139 + 8694839 = 8694978

Showing the first eight; more decompositions exist.
