Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139994, here are decompositions:

3 + 139991 = 139994
7 + 139987 = 139994
13 + 139981 = 139994
73 + 139921 = 139994
103 + 139891 = 139994
157 + 139837 = 139994
163 + 139831 = 139994
181 + 139813 = 139994

Showing the first eight; more decompositions exist.
