Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139980, here are decompositions:

11 + 139969 = 139980
13 + 139967 = 139980
37 + 139943 = 139980
41 + 139939 = 139980
59 + 139921 = 139980
73 + 139907 = 139980
79 + 139901 = 139980
89 + 139891 = 139980

Showing the first eight; more decompositions exist.
