Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002690, here are decompositions:

11 + 1002679 = 1002690
37 + 1002653 = 1002690
43 + 1002647 = 1002690
67 + 1002623 = 1002690
71 + 1002619 = 1002690
107 + 1002583 = 1002690
113 + 1002577 = 1002690
137 + 1002553 = 1002690

Showing the first eight; more decompositions exist.
