Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90170, here are decompositions:

7 + 90163 = 90170
43 + 90127 = 90170
97 + 90073 = 90170
103 + 90067 = 90170
139 + 90031 = 90170
151 + 90019 = 90170
163 + 90007 = 90170
181 + 89989 = 90170

Showing the first eight; more decompositions exist.
