Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001986, here are decompositions:

3 + 1001983 = 1001986
5 + 1001981 = 1001986
53 + 1001933 = 1001986
179 + 1001807 = 1001986
263 + 1001723 = 1001986
317 + 1001669 = 1001986
347 + 1001639 = 1001986
599 + 1001387 = 1001986

Showing the first eight; more decompositions exist.
