Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523724, here are decompositions:

7 + 523717 = 523724
43 + 523681 = 523724
67 + 523657 = 523724
127 + 523597 = 523724
151 + 523573 = 523724
181 + 523543 = 523724
307 + 523417 = 523724
337 + 523387 = 523724

Showing the first eight; more decompositions exist.
