Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520790, here are decompositions:

3 + 520787 = 520790
31 + 520759 = 520790
43 + 520747 = 520790
73 + 520717 = 520790
157 + 520633 = 520790
181 + 520609 = 520790
223 + 520567 = 520790
241 + 520549 = 520790

Showing the first eight; more decompositions exist.
