Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998888, here are decompositions:

31 + 998857 = 998888
109 + 998779 = 998888
139 + 998749 = 998888
151 + 998737 = 998888
199 + 998689 = 998888
271 + 998617 = 998888
337 + 998551 = 998888
349 + 998539 = 998888

Showing the first eight; more decompositions exist.
