Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987226, here are decompositions:

17 + 987209 = 987226
83 + 987143 = 987226
137 + 987089 = 987226
173 + 987053 = 987226
197 + 987029 = 987226
263 + 986963 = 987226
293 + 986933 = 987226
389 + 986837 = 987226

Showing the first eight; more decompositions exist.
