Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633988, here are decompositions:

5 + 8633983 = 8633988
7 + 8633981 = 8633988
17 + 8633971 = 8633988
29 + 8633959 = 8633988
31 + 8633957 = 8633988
37 + 8633951 = 8633988
47 + 8633941 = 8633988
67 + 8633921 = 8633988

Showing the first eight; more decompositions exist.
