Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83842, here are decompositions:

29 + 83813 = 83842
179 + 83663 = 83842
233 + 83609 = 83842
251 + 83591 = 83842
263 + 83579 = 83842
281 + 83561 = 83842
383 + 83459 = 83842
419 + 83423 = 83842

Showing the first eight; more decompositions exist.
