Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028684, here are decompositions:

3 + 1028681 = 1028684
37 + 1028647 = 1028684
67 + 1028617 = 1028684
103 + 1028581 = 1028684
127 + 1028557 = 1028684
211 + 1028473 = 1028684
367 + 1028317 = 1028684
421 + 1028263 = 1028684

Showing the first eight; more decompositions exist.
