Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523818, here are decompositions:

17 + 523801 = 523818
41 + 523777 = 523818
47 + 523771 = 523818
59 + 523759 = 523818
89 + 523729 = 523818
101 + 523717 = 523818
137 + 523681 = 523818
149 + 523669 = 523818

Showing the first eight; more decompositions exist.
