Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4740, here are decompositions:

7 + 4733 = 4740
11 + 4729 = 4740
17 + 4723 = 4740
19 + 4721 = 4740
37 + 4703 = 4740
61 + 4679 = 4740
67 + 4673 = 4740
83 + 4657 = 4740

Showing the first eight; more decompositions exist.
