Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653980, here are decompositions:

17 + 8653963 = 8653980
43 + 8653937 = 8653980
89 + 8653891 = 8653980
103 + 8653877 = 8653980
163 + 8653817 = 8653980
173 + 8653807 = 8653980
191 + 8653789 = 8653980
211 + 8653769 = 8653980

Showing the first eight; more decompositions exist.
