Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998986, here are decompositions:

3 + 998983 = 998986
17 + 998969 = 998986
29 + 998957 = 998986
59 + 998927 = 998986
89 + 998897 = 998986
167 + 998819 = 998986
173 + 998813 = 998986
227 + 998759 = 998986

Showing the first eight; more decompositions exist.
