Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002628, here are decompositions:

5 + 1002623 = 1002628
59 + 1002569 = 1002628
101 + 1002527 = 1002628
251 + 1002377 = 1002628
269 + 1002359 = 1002628
281 + 1002347 = 1002628
401 + 1002227 = 1002628
479 + 1002149 = 1002628

Showing the first eight; more decompositions exist.
