Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13730, here are decompositions:

7 + 13723 = 13730
19 + 13711 = 13730
37 + 13693 = 13730
43 + 13687 = 13730
61 + 13669 = 13730
97 + 13633 = 13730
103 + 13627 = 13730
139 + 13591 = 13730

Showing the first eight; more decompositions exist.
