Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39844, here are decompositions:

3 + 39841 = 39844
5 + 39839 = 39844
17 + 39827 = 39844
23 + 39821 = 39844
53 + 39791 = 39844
83 + 39761 = 39844
173 + 39671 = 39844
263 + 39581 = 39844

Showing the first eight; more decompositions exist.
