Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4728, here are decompositions:

5 + 4723 = 4728
7 + 4721 = 4728
37 + 4691 = 4728
71 + 4657 = 4728
79 + 4649 = 4728
89 + 4639 = 4728
107 + 4621 = 4728
131 + 4597 = 4728

Showing the first eight; more decompositions exist.
