Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4770, here are decompositions:

11 + 4759 = 4770
19 + 4751 = 4770
37 + 4733 = 4770
41 + 4729 = 4770
47 + 4723 = 4770
67 + 4703 = 4770
79 + 4691 = 4770
97 + 4673 = 4770

Showing the first eight; more decompositions exist.
