Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987396, here are decompositions:

5 + 987391 = 987396
13 + 987383 = 987396
43 + 987353 = 987396
83 + 987313 = 987396
97 + 987299 = 987396
103 + 987293 = 987396
197 + 987199 = 987396
269 + 987127 = 987396

Showing the first eight; more decompositions exist.
