Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986858, here are decompositions:

7 + 986851 = 986858
79 + 986779 = 986858
109 + 986749 = 986858
139 + 986719 = 986858
151 + 986707 = 986858
199 + 986659 = 986858
241 + 986617 = 986858
277 + 986581 = 986858

Showing the first eight; more decompositions exist.
