Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028080, here are decompositions:

17 + 1028063 = 1028080
29 + 1028051 = 1028080
149 + 1027931 = 1028080
197 + 1027883 = 1028080
227 + 1027853 = 1028080
239 + 1027841 = 1028080
281 + 1027799 = 1028080
293 + 1027787 = 1028080

Showing the first eight; more decompositions exist.
