Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520940, here are decompositions:

19 + 520921 = 520940
73 + 520867 = 520940
103 + 520837 = 520940
127 + 520813 = 520940
181 + 520759 = 520940
193 + 520747 = 520940
223 + 520717 = 520940
241 + 520699 = 520940

Showing the first eight; more decompositions exist.
