Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490478, here are decompositions:

19 + 490459 = 490478
61 + 490417 = 490478
139 + 490339 = 490478
211 + 490267 = 490478
229 + 490249 = 490478
271 + 490207 = 490478
277 + 490201 = 490478
367 + 490111 = 490478

Showing the first eight; more decompositions exist.
