Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051668, here are decompositions:

5 + 1051663 = 1051668
19 + 1051649 = 1051668
29 + 1051639 = 1051668
47 + 1051621 = 1051668
61 + 1051607 = 1051668
67 + 1051601 = 1051668
97 + 1051571 = 1051668
109 + 1051559 = 1051668

Showing the first eight; more decompositions exist.
