Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61680, here are decompositions:

7 + 61673 = 61680
13 + 61667 = 61680
23 + 61657 = 61680
29 + 61651 = 61680
37 + 61643 = 61680
43 + 61637 = 61680
53 + 61627 = 61680
67 + 61613 = 61680

Showing the first eight; more decompositions exist.
