Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502542, here are decompositions:

41 + 502501 = 502542
43 + 502499 = 502542
101 + 502441 = 502542
113 + 502429 = 502542
149 + 502393 = 502542
241 + 502301 = 502542
281 + 502261 = 502542
283 + 502259 = 502542

Showing the first eight; more decompositions exist.
