Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490138, here are decompositions:

17 + 490121 = 490138
41 + 490097 = 490138
107 + 490031 = 490138
137 + 490001 = 490138
149 + 489989 = 490138
179 + 489959 = 490138
197 + 489941 = 490138
227 + 489911 = 490138

Showing the first eight; more decompositions exist.
