Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676978, here are decompositions:

5 + 8676973 = 8676978
7 + 8676971 = 8676978
29 + 8676949 = 8676978
41 + 8676937 = 8676978
131 + 8676847 = 8676978
151 + 8676827 = 8676978
157 + 8676821 = 8676978
179 + 8676799 = 8676978

Showing the first eight; more decompositions exist.
