Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986138, here are decompositions:

7 + 986131 = 986138
37 + 986101 = 986138
67 + 986071 = 986138
157 + 985981 = 986138
271 + 985867 = 986138
331 + 985807 = 986138
379 + 985759 = 986138
397 + 985741 = 986138

Showing the first eight; more decompositions exist.
