Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494628, here are decompositions:

7 + 494621 = 494628
11 + 494617 = 494628
19 + 494609 = 494628
37 + 494591 = 494628
41 + 494587 = 494628
61 + 494567 = 494628
67 + 494561 = 494628
89 + 494539 = 494628

Showing the first eight; more decompositions exist.
