Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998874, here are decompositions:

13 + 998861 = 998874
17 + 998857 = 998874
31 + 998843 = 998874
43 + 998831 = 998874
61 + 998813 = 998874
131 + 998743 = 998874
137 + 998737 = 998874
157 + 998717 = 998874

Showing the first eight; more decompositions exist.
