Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490228, here are decompositions:

5 + 490223 = 490228
59 + 490169 = 490228
107 + 490121 = 490228
131 + 490097 = 490228
197 + 490031 = 490228
227 + 490001 = 490228
239 + 489989 = 490228
251 + 489977 = 490228

Showing the first eight; more decompositions exist.
