Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139308, here are decompositions:

5 + 139303 = 139308
7 + 139301 = 139308
11 + 139297 = 139308
17 + 139291 = 139308
41 + 139267 = 139308
67 + 139241 = 139308
107 + 139201 = 139308
109 + 139199 = 139308

Showing the first eight; more decompositions exist.
