Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986888, here are decompositions:

31 + 986857 = 986888
37 + 986851 = 986888
109 + 986779 = 986888
139 + 986749 = 986888
151 + 986737 = 986888
181 + 986707 = 986888
229 + 986659 = 986888
271 + 986617 = 986888

Showing the first eight; more decompositions exist.
