Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89158, here are decompositions:

5 + 89153 = 89158
71 + 89087 = 89158
89 + 89069 = 89158
101 + 89057 = 89158
107 + 89051 = 89158
137 + 89021 = 89158
149 + 89009 = 89158
239 + 88919 = 89158

Showing the first eight; more decompositions exist.
