Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051660, here are decompositions:

11 + 1051649 = 1051660
17 + 1051643 = 1051660
41 + 1051619 = 1051660
53 + 1051607 = 1051660
59 + 1051601 = 1051660
89 + 1051571 = 1051660
101 + 1051559 = 1051660
107 + 1051553 = 1051660

Showing the first eight; more decompositions exist.
