Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520612, here are decompositions:

3 + 520609 = 520612
5 + 520607 = 520612
23 + 520589 = 520612
41 + 520571 = 520612
83 + 520529 = 520612
179 + 520433 = 520612
233 + 520379 = 520612
251 + 520361 = 520612

Showing the first eight; more decompositions exist.
