Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502640, here are decompositions:

7 + 502633 = 502640
43 + 502597 = 502640
97 + 502543 = 502640
139 + 502501 = 502640
199 + 502441 = 502640
211 + 502429 = 502640
379 + 502261 = 502640
499 + 502141 = 502640

Showing the first eight; more decompositions exist.
