Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630988, here are decompositions:

5 + 8630983 = 8630988
17 + 8630971 = 8630988
59 + 8630929 = 8630988
89 + 8630899 = 8630988
127 + 8630861 = 8630988
131 + 8630857 = 8630988
137 + 8630851 = 8630988
151 + 8630837 = 8630988

Showing the first eight; more decompositions exist.
