Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987316, here are decompositions:

3 + 987313 = 987316
17 + 987299 = 987316
23 + 987293 = 987316
89 + 987227 = 987316
107 + 987209 = 987316
173 + 987143 = 987316
227 + 987089 = 987316
233 + 987083 = 987316

Showing the first eight; more decompositions exist.
