Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697978, here are decompositions:

5 + 8697973 = 8697978
7 + 8697971 = 8697978
11 + 8697967 = 8697978
31 + 8697947 = 8697978
41 + 8697937 = 8697978
59 + 8697919 = 8697978
89 + 8697889 = 8697978
109 + 8697869 = 8697978

Showing the first eight; more decompositions exist.
