Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490026, here are decompositions:

7 + 490019 = 490026
23 + 490003 = 490026
37 + 489989 = 490026
67 + 489959 = 490026
83 + 489943 = 490026
113 + 489913 = 490026
139 + 489887 = 490026
157 + 489869 = 490026

Showing the first eight; more decompositions exist.
