Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83938, here are decompositions:

5 + 83933 = 83938
17 + 83921 = 83938
47 + 83891 = 83938
317 + 83621 = 83938
347 + 83591 = 83938
359 + 83579 = 83938
401 + 83537 = 83938
461 + 83477 = 83938

Showing the first eight; more decompositions exist.
