Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498790, here are decompositions:

3 + 498787 = 498790
11 + 498779 = 498790
23 + 498767 = 498790
29 + 498761 = 498790
41 + 498749 = 498790
101 + 498689 = 498790
137 + 498653 = 498790
179 + 498611 = 498790

Showing the first eight; more decompositions exist.
