Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498858, here are decompositions:

67 + 498791 = 498858
71 + 498787 = 498858
79 + 498779 = 498858
97 + 498761 = 498858
109 + 498749 = 498858
167 + 498691 = 498858
179 + 498679 = 498858
211 + 498647 = 498858

Showing the first eight; more decompositions exist.
