Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635988, here are decompositions:

7 + 8635981 = 8635988
19 + 8635969 = 8635988
37 + 8635951 = 8635988
61 + 8635927 = 8635988
139 + 8635849 = 8635988
211 + 8635777 = 8635988
271 + 8635717 = 8635988
331 + 8635657 = 8635988

Showing the first eight; more decompositions exist.
