Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490802, here are decompositions:

19 + 490783 = 490802
31 + 490771 = 490802
61 + 490741 = 490802
139 + 490663 = 490802
211 + 490591 = 490802
223 + 490579 = 490802
229 + 490573 = 490802
283 + 490519 = 490802

Showing the first eight; more decompositions exist.
