Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025688, here are decompositions:

19 + 1025669 = 1025688
29 + 1025659 = 1025688
47 + 1025641 = 1025688
67 + 1025621 = 1025688
109 + 1025579 = 1025688
127 + 1025561 = 1025688
137 + 1025551 = 1025688
151 + 1025537 = 1025688

Showing the first eight; more decompositions exist.
