Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4668, here are decompositions:

5 + 4663 = 4668
11 + 4657 = 4668
17 + 4651 = 4668
19 + 4649 = 4668
29 + 4639 = 4668
31 + 4637 = 4668
47 + 4621 = 4668
71 + 4597 = 4668

Showing the first eight; more decompositions exist.
