Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502688, here are decompositions:

19 + 502669 = 502688
37 + 502651 = 502688
97 + 502591 = 502688
139 + 502549 = 502688
181 + 502507 = 502688
349 + 502339 = 502688
367 + 502321 = 502688
547 + 502141 = 502688

Showing the first eight; more decompositions exist.
