Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90128, here are decompositions:

7 + 90121 = 90128
61 + 90067 = 90128
97 + 90031 = 90128
109 + 90019 = 90128
127 + 90001 = 90128
139 + 89989 = 90128
151 + 89977 = 90128
211 + 89917 = 90128

Showing the first eight; more decompositions exist.
