Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028686, here are decompositions:

3 + 1028683 = 1028686
5 + 1028681 = 1028686
17 + 1028669 = 1028686
23 + 1028663 = 1028686
89 + 1028597 = 1028686
107 + 1028579 = 1028686
293 + 1028393 = 1028686
353 + 1028333 = 1028686

Showing the first eight; more decompositions exist.
