Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002782, here are decompositions:

13 + 1002769 = 1002782
31 + 1002751 = 1002782
43 + 1002739 = 1002782
61 + 1002721 = 1002782
73 + 1002709 = 1002782
103 + 1002679 = 1002782
163 + 1002619 = 1002782
199 + 1002583 = 1002782

Showing the first eight; more decompositions exist.
