Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045428, here are decompositions:

5 + 1045423 = 1045428
17 + 1045411 = 1045428
19 + 1045409 = 1045428
31 + 1045397 = 1045428
37 + 1045391 = 1045428
61 + 1045367 = 1045428
79 + 1045349 = 1045428
107 + 1045321 = 1045428

Showing the first eight; more decompositions exist.
