Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70940, here are decompositions:

3 + 70937 = 70940
19 + 70921 = 70940
61 + 70879 = 70940
73 + 70867 = 70940
97 + 70843 = 70940
157 + 70783 = 70940
211 + 70729 = 70940
223 + 70717 = 70940

Showing the first eight; more decompositions exist.
