Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487198, here are decompositions:

11 + 487187 = 487198
149 + 487049 = 487198
191 + 487007 = 487198
227 + 486971 = 487198
251 + 486947 = 487198
269 + 486929 = 487198
359 + 486839 = 487198
401 + 486797 = 487198

Showing the first eight; more decompositions exist.
