Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987238, here are decompositions:

11 + 987227 = 987238
29 + 987209 = 987238
47 + 987191 = 987238
137 + 987101 = 987238
149 + 987089 = 987238
257 + 986981 = 987238
311 + 986927 = 987238
389 + 986849 = 987238

Showing the first eight; more decompositions exist.
