Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043986, here are decompositions:

5 + 1043981 = 1043986
17 + 1043969 = 1043986
89 + 1043897 = 1043986
113 + 1043873 = 1043986
137 + 1043849 = 1043986
149 + 1043837 = 1043986
227 + 1043759 = 1043986
233 + 1043753 = 1043986

Showing the first eight; more decompositions exist.
