Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494590, here are decompositions:

3 + 494587 = 494590
23 + 494567 = 494590
29 + 494561 = 494590
71 + 494519 = 494590
149 + 494441 = 494590
263 + 494327 = 494590
353 + 494237 = 494590
443 + 494147 = 494590

Showing the first eight; more decompositions exist.
