Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027428, here are decompositions:

7 + 1027421 = 1027428
11 + 1027417 = 1027428
19 + 1027409 = 1027428
37 + 1027391 = 1027428
71 + 1027357 = 1027428
97 + 1027331 = 1027428
107 + 1027321 = 1027428
109 + 1027319 = 1027428

Showing the first eight; more decompositions exist.
