Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986886, here are decompositions:

29 + 986857 = 986886
37 + 986849 = 986886
67 + 986819 = 986886
73 + 986813 = 986886
107 + 986779 = 986886
127 + 986759 = 986886
137 + 986749 = 986886
149 + 986737 = 986886

Showing the first eight; more decompositions exist.
