Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989186, here are decompositions:

13 + 989173 = 989186
67 + 989119 = 989186
127 + 989059 = 989186
157 + 989029 = 989186
223 + 988963 = 989186
277 + 988909 = 989186
337 + 988849 = 989186
349 + 988837 = 989186

Showing the first eight; more decompositions exist.
