Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998854, here are decompositions:

11 + 998843 = 998854
23 + 998831 = 998854
41 + 998813 = 998854
137 + 998717 = 998854
167 + 998687 = 998854
173 + 998681 = 998854
293 + 998561 = 998854
317 + 998537 = 998854

Showing the first eight; more decompositions exist.
