Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139016, here are decompositions:

79 + 138937 = 139016
127 + 138889 = 139016
223 + 138793 = 139016
277 + 138739 = 139016
337 + 138679 = 139016
379 + 138637 = 139016
439 + 138577 = 139016
457 + 138559 = 139016

Showing the first eight; more decompositions exist.
