Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621150, here are decompositions:

3 + 8621147 = 8621150
7 + 8621143 = 8621150
61 + 8621089 = 8621150
67 + 8621083 = 8621150
73 + 8621077 = 8621150
103 + 8621047 = 8621150
157 + 8620993 = 8621150
199 + 8620951 = 8621150

Showing the first eight; more decompositions exist.
