Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43730, here are decompositions:

13 + 43717 = 43730
19 + 43711 = 43730
61 + 43669 = 43730
79 + 43651 = 43730
97 + 43633 = 43730
103 + 43627 = 43730
139 + 43591 = 43730
151 + 43579 = 43730

Showing the first eight; more decompositions exist.
