Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139998, here are decompositions:

7 + 139991 = 139998
11 + 139987 = 139998
17 + 139981 = 139998
29 + 139969 = 139998
31 + 139967 = 139998
59 + 139939 = 139998
97 + 139901 = 139998
107 + 139891 = 139998

Showing the first eight; more decompositions exist.
