Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621190, here are decompositions:

7 + 8621183 = 8621190
37 + 8621153 = 8621190
43 + 8621147 = 8621190
47 + 8621143 = 8621190
89 + 8621101 = 8621190
101 + 8621089 = 8621190
103 + 8621087 = 8621190
107 + 8621083 = 8621190

Showing the first eight; more decompositions exist.
