Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490030, here are decompositions:

11 + 490019 = 490030
29 + 490001 = 490030
41 + 489989 = 490030
53 + 489977 = 490030
71 + 489959 = 490030
89 + 489941 = 490030
179 + 489851 = 490030
197 + 489833 = 490030

Showing the first eight; more decompositions exist.
