Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23680, here are decompositions:

3 + 23677 = 23680
11 + 23669 = 23680
17 + 23663 = 23680
47 + 23633 = 23680
53 + 23627 = 23680
71 + 23609 = 23680
113 + 23567 = 23680
131 + 23549 = 23680

Showing the first eight; more decompositions exist.
