Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498838, here are decompositions:

5 + 498833 = 498838
47 + 498791 = 498838
59 + 498779 = 498838
71 + 498767 = 498838
89 + 498749 = 498838
149 + 498689 = 498838
191 + 498647 = 498838
227 + 498611 = 498838

Showing the first eight; more decompositions exist.
