Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987398, here are decompositions:

7 + 987391 = 987398
37 + 987361 = 987398
199 + 987199 = 987398
271 + 987127 = 987398
331 + 987067 = 987398
337 + 987061 = 987398
409 + 986989 = 987398
439 + 986959 = 987398

Showing the first eight; more decompositions exist.
