Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000668, here are decompositions:

17 + 1000651 = 1000668
29 + 1000639 = 1000668
47 + 1000621 = 1000668
59 + 1000609 = 1000668
79 + 1000589 = 1000668
89 + 1000579 = 1000668
127 + 1000541 = 1000668
131 + 1000537 = 1000668

Showing the first eight; more decompositions exist.
