Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660390, here are decompositions:

3 + 8660387 = 8660390
7 + 8660383 = 8660390
103 + 8660287 = 8660390
127 + 8660263 = 8660390
157 + 8660233 = 8660390
163 + 8660227 = 8660390
229 + 8660161 = 8660390
283 + 8660107 = 8660390

Showing the first eight; more decompositions exist.
