Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4860, here are decompositions:

29 + 4831 = 4860
43 + 4817 = 4860
47 + 4813 = 4860
59 + 4801 = 4860
61 + 4799 = 4860
67 + 4793 = 4860
71 + 4789 = 4860
73 + 4787 = 4860

Showing the first eight; more decompositions exist.
