Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499628, here are decompositions:

7 + 499621 = 499628
37 + 499591 = 499628
79 + 499549 = 499628
109 + 499519 = 499628
307 + 499321 = 499628
439 + 499189 = 499628
487 + 499141 = 499628
499 + 499129 = 499628

Showing the first eight; more decompositions exist.
