Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43942, here are decompositions:

29 + 43913 = 43942
53 + 43889 = 43942
89 + 43853 = 43942
149 + 43793 = 43942
251 + 43691 = 43942
281 + 43661 = 43942
293 + 43649 = 43942
401 + 43541 = 43942

Showing the first eight; more decompositions exist.
