Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520780, here are decompositions:

17 + 520763 = 520780
59 + 520721 = 520780
89 + 520691 = 520780
101 + 520679 = 520780
131 + 520649 = 520780
149 + 520631 = 520780
173 + 520607 = 520780
191 + 520589 = 520780

Showing the first eight; more decompositions exist.
