Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498900, here are decompositions:

19 + 498881 = 498900
41 + 498859 = 498900
43 + 498857 = 498900
67 + 498833 = 498900
97 + 498803 = 498900
109 + 498791 = 498900
113 + 498787 = 498900
139 + 498761 = 498900

Showing the first eight; more decompositions exist.
