Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490164, here are decompositions:

5 + 490159 = 490164
13 + 490151 = 490164
43 + 490121 = 490164
47 + 490117 = 490164
53 + 490111 = 490164
61 + 490103 = 490164
67 + 490097 = 490164
107 + 490057 = 490164

Showing the first eight; more decompositions exist.
