Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002636, here are decompositions:

13 + 1002623 = 1002636
17 + 1002619 = 1002636
53 + 1002583 = 1002636
59 + 1002577 = 1002636
67 + 1002569 = 1002636
83 + 1002553 = 1002636
109 + 1002527 = 1002636
113 + 1002523 = 1002636

Showing the first eight; more decompositions exist.
