Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39856, here are decompositions:

17 + 39839 = 39856
29 + 39827 = 39856
107 + 39749 = 39856
137 + 39719 = 39856
197 + 39659 = 39856
233 + 39623 = 39856
293 + 39563 = 39856
347 + 39509 = 39856

Showing the first eight; more decompositions exist.
