Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502742, here are decompositions:

13 + 502729 = 502742
43 + 502699 = 502742
73 + 502669 = 502742
109 + 502633 = 502742
151 + 502591 = 502742
193 + 502549 = 502742
199 + 502543 = 502742
241 + 502501 = 502742

Showing the first eight; more decompositions exist.
