Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139716, here are decompositions:

7 + 139709 = 139716
13 + 139703 = 139716
19 + 139697 = 139716
53 + 139663 = 139716
89 + 139627 = 139716
97 + 139619 = 139716
107 + 139609 = 139716
127 + 139589 = 139716

Showing the first eight; more decompositions exist.
