Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490004, here are decompositions:

3 + 490001 = 490004
43 + 489961 = 490004
61 + 489943 = 490004
103 + 489901 = 490004
157 + 489847 = 490004
181 + 489823 = 490004
211 + 489793 = 490004
271 + 489733 = 490004

Showing the first eight; more decompositions exist.
