Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987366, here are decompositions:

5 + 987361 = 987366
13 + 987353 = 987366
53 + 987313 = 987366
67 + 987299 = 987366
73 + 987293 = 987366
139 + 987227 = 987366
157 + 987209 = 987366
167 + 987199 = 987366

Showing the first eight; more decompositions exist.
