Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028688, here are decompositions:

5 + 1028683 = 1028688
7 + 1028681 = 1028688
19 + 1028669 = 1028688
41 + 1028647 = 1028688
71 + 1028617 = 1028688
107 + 1028581 = 1028688
109 + 1028579 = 1028688
127 + 1028561 = 1028688

Showing the first eight; more decompositions exist.
