Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523898, here are decompositions:

31 + 523867 = 523898
97 + 523801 = 523898
127 + 523771 = 523898
139 + 523759 = 523898
157 + 523741 = 523898
181 + 523717 = 523898
229 + 523669 = 523898
241 + 523657 = 523898

Showing the first eight; more decompositions exist.
