Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90458, here are decompositions:

19 + 90439 = 90458
61 + 90397 = 90458
79 + 90379 = 90458
211 + 90247 = 90458
241 + 90217 = 90458
271 + 90187 = 90458
331 + 90127 = 90458
337 + 90121 = 90458

Showing the first eight; more decompositions exist.
