Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693220, here are decompositions:

7 + 8693213 = 8693220
13 + 8693207 = 8693220
23 + 8693197 = 8693220
47 + 8693173 = 8693220
59 + 8693161 = 8693220
61 + 8693159 = 8693220
89 + 8693131 = 8693220
103 + 8693117 = 8693220

Showing the first eight; more decompositions exist.
