Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002586, here are decompositions:

3 + 1002583 = 1002586
17 + 1002569 = 1002586
59 + 1002527 = 1002586
83 + 1002503 = 1002586
227 + 1002359 = 1002586
239 + 1002347 = 1002586
359 + 1002227 = 1002586
443 + 1002143 = 1002586

Showing the first eight; more decompositions exist.
