Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690220, here are decompositions:

17 + 8690203 = 8690220
29 + 8690191 = 8690220
43 + 8690177 = 8690220
47 + 8690173 = 8690220
101 + 8690119 = 8690220
103 + 8690117 = 8690220
127 + 8690093 = 8690220
131 + 8690089 = 8690220

Showing the first eight; more decompositions exist.
