Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520630, here are decompositions:

23 + 520607 = 520630
41 + 520589 = 520630
59 + 520571 = 520630
83 + 520547 = 520630
101 + 520529 = 520630
179 + 520451 = 520630
197 + 520433 = 520630
251 + 520379 = 520630

Showing the first eight; more decompositions exist.
