Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990022, here are decompositions:

23 + 989999 = 990022
41 + 989981 = 990022
71 + 989951 = 990022
83 + 989939 = 990022
101 + 989921 = 990022
113 + 989909 = 990022
149 + 989873 = 990022
191 + 989831 = 990022

Showing the first eight; more decompositions exist.
