Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139446, here are decompositions:

7 + 139439 = 139446
17 + 139429 = 139446
23 + 139423 = 139446
37 + 139409 = 139446
53 + 139393 = 139446
59 + 139387 = 139446
79 + 139367 = 139446
103 + 139343 = 139446

Showing the first eight; more decompositions exist.
