Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90212, here are decompositions:

13 + 90199 = 90212
139 + 90073 = 90212
181 + 90031 = 90212
193 + 90019 = 90212
211 + 90001 = 90212
223 + 89989 = 90212
229 + 89983 = 90212
313 + 89899 = 90212

Showing the first eight; more decompositions exist.
