Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494730, here are decompositions:

7 + 494723 = 494730
11 + 494719 = 494730
17 + 494713 = 494730
31 + 494699 = 494730
37 + 494693 = 494730
43 + 494687 = 494730
53 + 494677 = 494730
59 + 494671 = 494730

Showing the first eight; more decompositions exist.
