Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83824, here are decompositions:

11 + 83813 = 83824
47 + 83777 = 83824
107 + 83717 = 83824
227 + 83597 = 83824
233 + 83591 = 83824
263 + 83561 = 83824
347 + 83477 = 83824
353 + 83471 = 83824

Showing the first eight; more decompositions exist.
