Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502442, here are decompositions:

13 + 502429 = 502442
103 + 502339 = 502442
181 + 502261 = 502442
271 + 502171 = 502442
349 + 502093 = 502442
379 + 502063 = 502442
601 + 501841 = 502442
613 + 501829 = 502442

Showing the first eight; more decompositions exist.
