Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520620, here are decompositions:

11 + 520609 = 520620
13 + 520607 = 520620
31 + 520589 = 520620
53 + 520567 = 520620
71 + 520549 = 520620
73 + 520547 = 520620
173 + 520447 = 520620
193 + 520427 = 520620

Showing the first eight; more decompositions exist.
