Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630020, here are decompositions:

17 + 8630003 = 8630020
59 + 8629961 = 8630020
71 + 8629949 = 8630020
131 + 8629889 = 8630020
137 + 8629883 = 8630020
173 + 8629847 = 8630020
197 + 8629823 = 8630020
257 + 8629763 = 8630020

Showing the first eight; more decompositions exist.
