Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002688, here are decompositions:

41 + 1002647 = 1002688
311 + 1002377 = 1002688
347 + 1002341 = 1002688
389 + 1002299 = 1002688
431 + 1002257 = 1002688
461 + 1002227 = 1002688
587 + 1002101 = 1002688
857 + 1001831 = 1002688

Showing the first eight; more decompositions exist.
