Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029388, here are decompositions:

5 + 1029383 = 1029388
29 + 1029359 = 1029388
47 + 1029341 = 1029388
137 + 1029251 = 1029388
179 + 1029209 = 1029388
197 + 1029191 = 1029388
389 + 1028999 = 1029388
419 + 1028969 = 1029388

Showing the first eight; more decompositions exist.
