Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90028, here are decompositions:

5 + 90023 = 90028
11 + 90017 = 90028
17 + 90011 = 90028
89 + 89939 = 90028
131 + 89897 = 90028
137 + 89891 = 90028
179 + 89849 = 90028
269 + 89759 = 90028

Showing the first eight; more decompositions exist.
