Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499838, here are decompositions:

19 + 499819 = 499838
37 + 499801 = 499838
109 + 499729 = 499838
127 + 499711 = 499838
151 + 499687 = 499838
331 + 499507 = 499838
379 + 499459 = 499838
571 + 499267 = 499838

Showing the first eight; more decompositions exist.
