Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490126, here are decompositions:

5 + 490121 = 490126
23 + 490103 = 490126
29 + 490097 = 490126
107 + 490019 = 490126
137 + 489989 = 490126
149 + 489977 = 490126
167 + 489959 = 490126
239 + 489887 = 490126

Showing the first eight; more decompositions exist.
