Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139398, here are decompositions:

5 + 139393 = 139398
11 + 139387 = 139398
29 + 139369 = 139398
31 + 139367 = 139398
37 + 139361 = 139398
59 + 139339 = 139398
89 + 139309 = 139398
97 + 139301 = 139398

Showing the first eight; more decompositions exist.
