Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4686, here are decompositions:

7 + 4679 = 4686
13 + 4673 = 4686
23 + 4663 = 4686
29 + 4657 = 4686
37 + 4649 = 4686
43 + 4643 = 4686
47 + 4639 = 4686
83 + 4603 = 4686

Showing the first eight; more decompositions exist.
