Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490122, here are decompositions:

5 + 490117 = 490122
11 + 490111 = 490122
19 + 490103 = 490122
89 + 490033 = 490122
103 + 490019 = 490122
163 + 489959 = 490122
179 + 489943 = 490122
181 + 489941 = 490122

Showing the first eight; more decompositions exist.
