Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986908, here are decompositions:

5 + 986903 = 986908
59 + 986849 = 986908
71 + 986837 = 986908
89 + 986819 = 986908
107 + 986801 = 986908
149 + 986759 = 986908
179 + 986729 = 986908
191 + 986717 = 986908

Showing the first eight; more decompositions exist.
