Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051428, here are decompositions:

5 + 1051423 = 1051428
11 + 1051417 = 1051428
19 + 1051409 = 1051428
31 + 1051397 = 1051428
109 + 1051319 = 1051428
127 + 1051301 = 1051428
137 + 1051291 = 1051428
151 + 1051277 = 1051428

Showing the first eight; more decompositions exist.
