Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520786, here are decompositions:

23 + 520763 = 520786
83 + 520703 = 520786
107 + 520679 = 520786
137 + 520649 = 520786
179 + 520607 = 520786
197 + 520589 = 520786
239 + 520547 = 520786
257 + 520529 = 520786

Showing the first eight; more decompositions exist.
