Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523680, here are decompositions:

7 + 523673 = 523680
11 + 523669 = 523680
13 + 523667 = 523680
23 + 523657 = 523680
41 + 523639 = 523680
43 + 523637 = 523680
83 + 523597 = 523680
103 + 523577 = 523680

Showing the first eight; more decompositions exist.
