Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139974, here are decompositions:

5 + 139969 = 139974
7 + 139967 = 139974
31 + 139943 = 139974
53 + 139921 = 139974
67 + 139907 = 139974
73 + 139901 = 139974
83 + 139891 = 139974
103 + 139871 = 139974

Showing the first eight; more decompositions exist.
