Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523820, here are decompositions:

19 + 523801 = 523820
43 + 523777 = 523820
61 + 523759 = 523820
79 + 523741 = 523820
103 + 523717 = 523820
139 + 523681 = 523820
151 + 523669 = 523820
163 + 523657 = 523820

Showing the first eight; more decompositions exist.
