Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998856, here are decompositions:

13 + 998843 = 998856
17 + 998839 = 998856
37 + 998819 = 998856
43 + 998813 = 998856
97 + 998759 = 998856
107 + 998749 = 998856
113 + 998743 = 998856
139 + 998717 = 998856

Showing the first eight; more decompositions exist.
