Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90158, here are decompositions:

31 + 90127 = 90158
37 + 90121 = 90158
127 + 90031 = 90158
139 + 90019 = 90158
151 + 90007 = 90158
157 + 90001 = 90158
181 + 89977 = 90158
199 + 89959 = 90158

Showing the first eight; more decompositions exist.
