Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139022, here are decompositions:

139 + 138883 = 139022
181 + 138841 = 139022
193 + 138829 = 139022
223 + 138799 = 139022
229 + 138793 = 139022
283 + 138739 = 139022
463 + 138559 = 139022
571 + 138451 = 139022

Showing the first eight; more decompositions exist.
