Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139434, here are decompositions:

5 + 139429 = 139434
11 + 139423 = 139434
37 + 139397 = 139434
41 + 139393 = 139434
47 + 139387 = 139434
67 + 139367 = 139434
73 + 139361 = 139434
101 + 139333 = 139434

Showing the first eight; more decompositions exist.
