Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652978, here are decompositions:

7 + 8652971 = 8652978
31 + 8652947 = 8652978
151 + 8652827 = 8652978
157 + 8652821 = 8652978
181 + 8652797 = 8652978
197 + 8652781 = 8652978
211 + 8652767 = 8652978
281 + 8652697 = 8652978

Showing the first eight; more decompositions exist.
