Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490038, here are decompositions:

5 + 490033 = 490038
7 + 490031 = 490038
19 + 490019 = 490038
37 + 490001 = 490038
61 + 489977 = 490038
79 + 489959 = 490038
97 + 489941 = 490038
127 + 489911 = 490038

Showing the first eight; more decompositions exist.
