Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7730, here are decompositions:

3 + 7727 = 7730
7 + 7723 = 7730
13 + 7717 = 7730
31 + 7699 = 7730
43 + 7687 = 7730
61 + 7669 = 7730
109 + 7621 = 7730
127 + 7603 = 7730

Showing the first eight; more decompositions exist.
