Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490200, here are decompositions:

17 + 490183 = 490200
31 + 490169 = 490200
41 + 490159 = 490200
79 + 490121 = 490200
83 + 490117 = 490200
89 + 490111 = 490200
97 + 490103 = 490200
103 + 490097 = 490200

Showing the first eight; more decompositions exist.
