Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490570, here are decompositions:

11 + 490559 = 490570
29 + 490541 = 490570
71 + 490499 = 490570
89 + 490481 = 490570
107 + 490463 = 490570
149 + 490421 = 490570
257 + 490313 = 490570
293 + 490277 = 490570

Showing the first eight; more decompositions exist.
