Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998872, here are decompositions:

11 + 998861 = 998872
29 + 998843 = 998872
41 + 998831 = 998872
53 + 998819 = 998872
59 + 998813 = 998872
113 + 998759 = 998872
191 + 998681 = 998872
239 + 998633 = 998872

Showing the first eight; more decompositions exist.
