Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490306, here are decompositions:

23 + 490283 = 490306
29 + 490277 = 490306
59 + 490247 = 490306
83 + 490223 = 490306
137 + 490169 = 490306
317 + 489989 = 490306
347 + 489959 = 490306
419 + 489887 = 490306

Showing the first eight; more decompositions exist.
