Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490236, here are decompositions:

13 + 490223 = 490236
29 + 490207 = 490236
53 + 490183 = 490236
67 + 490169 = 490236
139 + 490097 = 490236
179 + 490057 = 490236
233 + 490003 = 490236
277 + 489959 = 490236

Showing the first eight; more decompositions exist.
