Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520850, here are decompositions:

13 + 520837 = 520850
37 + 520813 = 520850
103 + 520747 = 520850
151 + 520699 = 520850
229 + 520621 = 520850
241 + 520609 = 520850
283 + 520567 = 520850
439 + 520411 = 520850

Showing the first eight; more decompositions exist.
