Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494688, here are decompositions:

11 + 494677 = 494688
17 + 494671 = 494688
37 + 494651 = 494688
41 + 494647 = 494688
67 + 494621 = 494688
71 + 494617 = 494688
79 + 494609 = 494688
97 + 494591 = 494688

Showing the first eight; more decompositions exist.
