Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490128, here are decompositions:

7 + 490121 = 490128
11 + 490117 = 490128
17 + 490111 = 490128
31 + 490097 = 490128
71 + 490057 = 490128
97 + 490031 = 490128
109 + 490019 = 490128
127 + 490001 = 490128

Showing the first eight; more decompositions exist.
