Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43940, here are decompositions:

7 + 43933 = 43940
73 + 43867 = 43940
139 + 43801 = 43940
151 + 43789 = 43940
157 + 43783 = 43940
163 + 43777 = 43940
181 + 43759 = 43940
223 + 43717 = 43940

Showing the first eight; more decompositions exist.
