Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608978, here are decompositions:

5 + 8608973 = 8608978
47 + 8608931 = 8608978
71 + 8608907 = 8608978
89 + 8608889 = 8608978
107 + 8608871 = 8608978
137 + 8608841 = 8608978
149 + 8608829 = 8608978
179 + 8608799 = 8608978

Showing the first eight; more decompositions exist.
