Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671998, here are decompositions:

7 + 8671991 = 8671998
11 + 8671987 = 8671998
17 + 8671981 = 8671998
19 + 8671979 = 8671998
31 + 8671967 = 8671998
61 + 8671937 = 8671998
79 + 8671919 = 8671998
229 + 8671769 = 8671998

Showing the first eight; more decompositions exist.
