Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029128, here are decompositions:

19 + 1029109 = 1029128
127 + 1029001 = 1029128
367 + 1028761 = 1029128
379 + 1028749 = 1029128
547 + 1028581 = 1029128
571 + 1028557 = 1029128
619 + 1028509 = 1029128
691 + 1028437 = 1029128

Showing the first eight; more decompositions exist.
