Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90210, here are decompositions:

7 + 90203 = 90210
11 + 90199 = 90210
13 + 90197 = 90210
19 + 90191 = 90210
23 + 90187 = 90210
37 + 90173 = 90210
47 + 90163 = 90210
61 + 90149 = 90210

Showing the first eight; more decompositions exist.
