Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139344, here are decompositions:

5 + 139339 = 139344
11 + 139333 = 139344
31 + 139313 = 139344
41 + 139303 = 139344
43 + 139301 = 139344
47 + 139297 = 139344
53 + 139291 = 139344
71 + 139273 = 139344

Showing the first eight; more decompositions exist.
