Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4806, here are decompositions:

5 + 4801 = 4806
7 + 4799 = 4806
13 + 4793 = 4806
17 + 4789 = 4806
19 + 4787 = 4806
23 + 4783 = 4806
47 + 4759 = 4806
73 + 4733 = 4806

Showing the first eight; more decompositions exist.
