Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640206, here are decompositions:

19 + 8640187 = 8640206
37 + 8640169 = 8640206
73 + 8640133 = 8640206
97 + 8640109 = 8640206
193 + 8640013 = 8640206
229 + 8639977 = 8640206
283 + 8639923 = 8640206
307 + 8639899 = 8640206

Showing the first eight; more decompositions exist.
