Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523686, here are decompositions:

5 + 523681 = 523686
13 + 523673 = 523686
17 + 523669 = 523686
19 + 523667 = 523686
29 + 523657 = 523686
47 + 523639 = 523686
83 + 523603 = 523686
89 + 523597 = 523686

Showing the first eight; more decompositions exist.
