Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499748, here are decompositions:

19 + 499729 = 499748
31 + 499717 = 499748
37 + 499711 = 499748
61 + 499687 = 499748
79 + 499669 = 499748
127 + 499621 = 499748
157 + 499591 = 499748
199 + 499549 = 499748

Showing the first eight; more decompositions exist.
