Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490168, here are decompositions:

17 + 490151 = 490168
47 + 490121 = 490168
71 + 490097 = 490168
137 + 490031 = 490168
149 + 490019 = 490168
167 + 490001 = 490168
179 + 489989 = 490168
191 + 489977 = 490168

Showing the first eight; more decompositions exist.
