Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520726, here are decompositions:

5 + 520721 = 520726
23 + 520703 = 520726
47 + 520679 = 520726
137 + 520589 = 520726
179 + 520547 = 520726
197 + 520529 = 520726
293 + 520433 = 520726
317 + 520409 = 520726

Showing the first eight; more decompositions exist.
