Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498816, here are decompositions:

13 + 498803 = 498816
29 + 498787 = 498816
37 + 498779 = 498816
67 + 498749 = 498816
83 + 498733 = 498816
127 + 498689 = 498816
137 + 498679 = 498816
163 + 498653 = 498816

Showing the first eight; more decompositions exist.
