Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523746, here are decompositions:

5 + 523741 = 523746
17 + 523729 = 523746
29 + 523717 = 523746
73 + 523673 = 523746
79 + 523667 = 523746
89 + 523657 = 523746
107 + 523639 = 523746
109 + 523637 = 523746

Showing the first eight; more decompositions exist.
