Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4730, here are decompositions:

7 + 4723 = 4730
67 + 4663 = 4730
73 + 4657 = 4730
79 + 4651 = 4730
109 + 4621 = 4730
127 + 4603 = 4730
139 + 4591 = 4730
163 + 4567 = 4730

Showing the first eight; more decompositions exist.
