Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139970, here are decompositions:

3 + 139967 = 139970
31 + 139939 = 139970
79 + 139891 = 139970
109 + 139861 = 139970
139 + 139831 = 139970
157 + 139813 = 139970
211 + 139759 = 139970
223 + 139747 = 139970

Showing the first eight; more decompositions exist.
