Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520648, here are decompositions:

17 + 520631 = 520648
41 + 520607 = 520648
59 + 520589 = 520648
101 + 520547 = 520648
197 + 520451 = 520648
239 + 520409 = 520648
269 + 520379 = 520648
617 + 520031 = 520648

Showing the first eight; more decompositions exist.
