Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001686, here are decompositions:

3 + 1001683 = 1001686
17 + 1001669 = 1001686
47 + 1001639 = 1001686
137 + 1001549 = 1001686
227 + 1001459 = 1001686
239 + 1001447 = 1001686
317 + 1001369 = 1001686
359 + 1001327 = 1001686

Showing the first eight; more decompositions exist.
