Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987364, here are decompositions:

3 + 987361 = 987364
11 + 987353 = 987364
71 + 987293 = 987364
113 + 987251 = 987364
137 + 987227 = 987364
173 + 987191 = 987364
263 + 987101 = 987364
281 + 987083 = 987364

Showing the first eight; more decompositions exist.
