Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633820, here are decompositions:

43 + 8633777 = 8633820
53 + 8633767 = 8633820
73 + 8633747 = 8633820
89 + 8633731 = 8633820
101 + 8633719 = 8633820
109 + 8633711 = 8633820
137 + 8633683 = 8633820
157 + 8633663 = 8633820

Showing the first eight; more decompositions exist.
