Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057428, here are decompositions:

7 + 1057421 = 1057428
17 + 1057411 = 1057428
37 + 1057391 = 1057428
41 + 1057387 = 1057428
61 + 1057367 = 1057428
67 + 1057361 = 1057428
137 + 1057291 = 1057428
149 + 1057279 = 1057428

Showing the first eight; more decompositions exist.
