Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140942, here are decompositions:

3 + 140939 = 140942
13 + 140929 = 140942
73 + 140869 = 140942
79 + 140863 = 140942
103 + 140839 = 140942
163 + 140779 = 140942
181 + 140761 = 140942
211 + 140731 = 140942

Showing the first eight; more decompositions exist.
