Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502490, here are decompositions:

3 + 502487 = 502490
61 + 502429 = 502490
97 + 502393 = 502490
151 + 502339 = 502490
229 + 502261 = 502490
349 + 502141 = 502490
397 + 502093 = 502490
409 + 502081 = 502490

Showing the first eight; more decompositions exist.
