Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987358, here are decompositions:

5 + 987353 = 987358
59 + 987299 = 987358
107 + 987251 = 987358
131 + 987227 = 987358
149 + 987209 = 987358
167 + 987191 = 987358
257 + 987101 = 987358
269 + 987089 = 987358

Showing the first eight; more decompositions exist.
