Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139338, here are decompositions:

5 + 139333 = 139338
29 + 139309 = 139338
37 + 139301 = 139338
41 + 139297 = 139338
47 + 139291 = 139338
71 + 139267 = 139338
97 + 139241 = 139338
137 + 139201 = 139338

Showing the first eight; more decompositions exist.
