Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4830, here are decompositions:

13 + 4817 = 4830
17 + 4813 = 4830
29 + 4801 = 4830
31 + 4799 = 4830
37 + 4793 = 4830
41 + 4789 = 4830
43 + 4787 = 4830
47 + 4783 = 4830

Showing the first eight; more decompositions exist.
