Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664978, here are decompositions:

17 + 8664961 = 8664978
19 + 8664959 = 8664978
29 + 8664949 = 8664978
31 + 8664947 = 8664978
37 + 8664941 = 8664978
71 + 8664907 = 8664978
107 + 8664871 = 8664978
109 + 8664869 = 8664978

Showing the first eight; more decompositions exist.
