Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43840, here are decompositions:

47 + 43793 = 43840
53 + 43787 = 43840
59 + 43781 = 43840
149 + 43691 = 43840
179 + 43661 = 43840
191 + 43649 = 43840
227 + 43613 = 43840
233 + 43607 = 43840

Showing the first eight; more decompositions exist.
