Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83872, here are decompositions:

3 + 83869 = 83872
29 + 83843 = 83872
59 + 83813 = 83872
233 + 83639 = 83872
251 + 83621 = 83872
263 + 83609 = 83872
281 + 83591 = 83872
293 + 83579 = 83872

Showing the first eight; more decompositions exist.
