Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987166, here are decompositions:

23 + 987143 = 987166
83 + 987083 = 987166
113 + 987053 = 987166
137 + 987029 = 987166
233 + 986933 = 987166
239 + 986927 = 987166
263 + 986903 = 987166
317 + 986849 = 987166

Showing the first eight; more decompositions exist.
