Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019428, here are decompositions:

5 + 1019423 = 1019428
17 + 1019411 = 1019428
29 + 1019399 = 1019428
71 + 1019357 = 1019428
89 + 1019339 = 1019428
131 + 1019297 = 1019428
167 + 1019261 = 1019428
191 + 1019237 = 1019428

Showing the first eight; more decompositions exist.
