Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028798, here are decompositions:

37 + 1028761 = 1028798
61 + 1028737 = 1028798
151 + 1028647 = 1028798
181 + 1028617 = 1028798
229 + 1028569 = 1028798
241 + 1028557 = 1028798
409 + 1028389 = 1028798
577 + 1028221 = 1028798

Showing the first eight; more decompositions exist.
