Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490814, here are decompositions:

31 + 490783 = 490814
43 + 490771 = 490814
73 + 490741 = 490814
151 + 490663 = 490814
223 + 490591 = 490814
241 + 490573 = 490814
271 + 490543 = 490814
277 + 490537 = 490814

Showing the first eight; more decompositions exist.
