Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002686, here are decompositions:

7 + 1002679 = 1002686
67 + 1002619 = 1002686
103 + 1002583 = 1002686
109 + 1002577 = 1002686
163 + 1002523 = 1002686
193 + 1002493 = 1002686
199 + 1002487 = 1002686
229 + 1002457 = 1002686

Showing the first eight; more decompositions exist.
