Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498778, here are decompositions:

11 + 498767 = 498778
17 + 498761 = 498778
29 + 498749 = 498778
89 + 498689 = 498778
131 + 498647 = 498778
167 + 498611 = 498778
179 + 498599 = 498778
227 + 498551 = 498778

Showing the first eight; more decompositions exist.
