Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490742, here are decompositions:

79 + 490663 = 490742
151 + 490591 = 490742
163 + 490579 = 490742
193 + 490549 = 490742
199 + 490543 = 490742
223 + 490519 = 490742
283 + 490459 = 490742
349 + 490393 = 490742

Showing the first eight; more decompositions exist.
