Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023428, here are decompositions:

19 + 1023409 = 1023428
37 + 1023391 = 1023428
61 + 1023367 = 1023428
67 + 1023361 = 1023428
127 + 1023301 = 1023428
139 + 1023289 = 1023428
151 + 1023277 = 1023428
199 + 1023229 = 1023428

Showing the first eight; more decompositions exist.
