Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140078, here are decompositions:

7 + 140071 = 140078
79 + 139999 = 140078
97 + 139981 = 140078
109 + 139969 = 140078
139 + 139939 = 140078
157 + 139921 = 140078
241 + 139837 = 140078
277 + 139801 = 140078

Showing the first eight; more decompositions exist.
