Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660208, here are decompositions:

5 + 8660203 = 8660208
19 + 8660189 = 8660208
31 + 8660177 = 8660208
47 + 8660161 = 8660208
101 + 8660107 = 8660208
127 + 8660081 = 8660208
131 + 8660077 = 8660208
157 + 8660051 = 8660208

Showing the first eight; more decompositions exist.
