Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43720, here are decompositions:

3 + 43717 = 43720
29 + 43691 = 43720
59 + 43661 = 43720
71 + 43649 = 43720
107 + 43613 = 43720
113 + 43607 = 43720
179 + 43541 = 43720
233 + 43487 = 43720

Showing the first eight; more decompositions exist.
