Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502644, here are decompositions:

11 + 502633 = 502644
13 + 502631 = 502644
31 + 502613 = 502644
47 + 502597 = 502644
53 + 502591 = 502644
101 + 502543 = 502644
127 + 502517 = 502644
137 + 502507 = 502644

Showing the first eight; more decompositions exist.
