Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051686, here are decompositions:

23 + 1051663 = 1051686
37 + 1051649 = 1051686
43 + 1051643 = 1051686
47 + 1051639 = 1051686
67 + 1051619 = 1051686
79 + 1051607 = 1051686
127 + 1051559 = 1051686
137 + 1051549 = 1051686

Showing the first eight; more decompositions exist.
