Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494650, here are decompositions:

3 + 494647 = 494650
11 + 494639 = 494650
29 + 494621 = 494650
41 + 494609 = 494650
59 + 494591 = 494650
83 + 494567 = 494650
89 + 494561 = 494650
131 + 494519 = 494650

Showing the first eight; more decompositions exist.
