Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494658, here are decompositions:

7 + 494651 = 494658
11 + 494647 = 494658
19 + 494639 = 494658
37 + 494621 = 494658
41 + 494617 = 494658
67 + 494591 = 494658
71 + 494587 = 494658
97 + 494561 = 494658

Showing the first eight; more decompositions exist.
