Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520686, here are decompositions:

7 + 520679 = 520686
37 + 520649 = 520686
53 + 520633 = 520686
79 + 520607 = 520686
97 + 520589 = 520686
137 + 520549 = 520686
139 + 520547 = 520686
157 + 520529 = 520686

Showing the first eight; more decompositions exist.
