Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139950, here are decompositions:

7 + 139943 = 139950
11 + 139939 = 139950
29 + 139921 = 139950
43 + 139907 = 139950
59 + 139891 = 139950
67 + 139883 = 139950
79 + 139871 = 139950
89 + 139861 = 139950

Showing the first eight; more decompositions exist.
