Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43738, here are decompositions:

17 + 43721 = 43738
47 + 43691 = 43738
89 + 43649 = 43738
131 + 43607 = 43738
197 + 43541 = 43738
239 + 43499 = 43738
251 + 43487 = 43738
257 + 43481 = 43738

Showing the first eight; more decompositions exist.
