Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520678, here are decompositions:

29 + 520649 = 520678
47 + 520631 = 520678
71 + 520607 = 520678
89 + 520589 = 520678
107 + 520571 = 520678
131 + 520547 = 520678
149 + 520529 = 520678
227 + 520451 = 520678

Showing the first eight; more decompositions exist.
