Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520836, here are decompositions:

23 + 520813 = 520836
73 + 520763 = 520836
89 + 520747 = 520836
137 + 520699 = 520836
157 + 520679 = 520836
227 + 520609 = 520836
229 + 520607 = 520836
269 + 520567 = 520836

Showing the first eight; more decompositions exist.
