Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490068, here are decompositions:

11 + 490057 = 490068
37 + 490031 = 490068
67 + 490001 = 490068
79 + 489989 = 490068
107 + 489961 = 490068
109 + 489959 = 490068
127 + 489941 = 490068
157 + 489911 = 490068

Showing the first eight; more decompositions exist.
