Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490284, here are decompositions:

7 + 490277 = 490284
13 + 490271 = 490284
17 + 490267 = 490284
37 + 490247 = 490284
43 + 490241 = 490284
61 + 490223 = 490284
83 + 490201 = 490284
101 + 490183 = 490284

Showing the first eight; more decompositions exist.
