Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051680, here are decompositions:

17 + 1051663 = 1051680
31 + 1051649 = 1051680
37 + 1051643 = 1051680
41 + 1051639 = 1051680
59 + 1051621 = 1051680
61 + 1051619 = 1051680
73 + 1051607 = 1051680
79 + 1051601 = 1051680

Showing the first eight; more decompositions exist.
