Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058428, here are decompositions:

5 + 1058423 = 1058428
47 + 1058381 = 1058428
89 + 1058339 = 1058428
179 + 1058249 = 1058428
257 + 1058171 = 1058428
281 + 1058147 = 1058428
311 + 1058117 = 1058428
401 + 1058027 = 1058428

Showing the first eight; more decompositions exist.
