Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695978, here are decompositions:

17 + 8695961 = 8695978
29 + 8695949 = 8695978
41 + 8695937 = 8695978
47 + 8695931 = 8695978
89 + 8695889 = 8695978
251 + 8695727 = 8695978
311 + 8695667 = 8695978
449 + 8695529 = 8695978

Showing the first eight; more decompositions exist.
