Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502438, here are decompositions:

17 + 502421 = 502438
29 + 502409 = 502438
137 + 502301 = 502438
179 + 502259 = 502438
191 + 502247 = 502438
257 + 502181 = 502438
317 + 502121 = 502438
359 + 502079 = 502438

Showing the first eight; more decompositions exist.
