Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490198, here are decompositions:

29 + 490169 = 490198
47 + 490151 = 490198
101 + 490097 = 490198
167 + 490031 = 490198
179 + 490019 = 490198
197 + 490001 = 490198
239 + 489959 = 490198
257 + 489941 = 490198

Showing the first eight; more decompositions exist.
