Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490180, here are decompositions:

11 + 490169 = 490180
29 + 490151 = 490180
59 + 490121 = 490180
83 + 490097 = 490180
149 + 490031 = 490180
179 + 490001 = 490180
191 + 489989 = 490180
239 + 489941 = 490180

Showing the first eight; more decompositions exist.
