Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4680, here are decompositions:

7 + 4673 = 4680
17 + 4663 = 4680
23 + 4657 = 4680
29 + 4651 = 4680
31 + 4649 = 4680
37 + 4643 = 4680
41 + 4639 = 4680
43 + 4637 = 4680

Showing the first eight; more decompositions exist.
