Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139266, here are decompositions:

67 + 139199 = 139266
79 + 139187 = 139266
89 + 139177 = 139266
97 + 139169 = 139266
157 + 139109 = 139266
199 + 139067 = 139266
233 + 139033 = 139266
307 + 138959 = 139266

Showing the first eight; more decompositions exist.
