Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502540, here are decompositions:

23 + 502517 = 502540
41 + 502499 = 502540
53 + 502487 = 502540
89 + 502451 = 502540
131 + 502409 = 502540
239 + 502301 = 502540
263 + 502277 = 502540
281 + 502259 = 502540

Showing the first eight; more decompositions exist.
