Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139458, here are decompositions:

19 + 139439 = 139458
29 + 139429 = 139458
61 + 139397 = 139458
71 + 139387 = 139458
89 + 139369 = 139458
97 + 139361 = 139458
149 + 139309 = 139458
157 + 139301 = 139458

Showing the first eight; more decompositions exist.
