Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502730, here are decompositions:

13 + 502717 = 502730
31 + 502699 = 502730
43 + 502687 = 502730
61 + 502669 = 502730
79 + 502651 = 502730
97 + 502633 = 502730
139 + 502591 = 502730
181 + 502549 = 502730

Showing the first eight; more decompositions exist.
