Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90218, here are decompositions:

19 + 90199 = 90218
31 + 90187 = 90218
97 + 90121 = 90218
151 + 90067 = 90218
199 + 90019 = 90218
211 + 90007 = 90218
229 + 89989 = 90218
241 + 89977 = 90218

Showing the first eight; more decompositions exist.
