Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523838, here are decompositions:

37 + 523801 = 523838
61 + 523777 = 523838
67 + 523771 = 523838
79 + 523759 = 523838
97 + 523741 = 523838
109 + 523729 = 523838
157 + 523681 = 523838
181 + 523657 = 523838

Showing the first eight; more decompositions exist.
