Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490386, here are decompositions:

19 + 490367 = 490386
47 + 490339 = 490386
73 + 490313 = 490386
103 + 490283 = 490386
109 + 490277 = 490386
137 + 490249 = 490386
139 + 490247 = 490386
163 + 490223 = 490386

Showing the first eight; more decompositions exist.
