Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17844, here are decompositions:

5 + 17839 = 17844
7 + 17837 = 17844
17 + 17827 = 17844
37 + 17807 = 17844
53 + 17791 = 17844
61 + 17783 = 17844
83 + 17761 = 17844
97 + 17747 = 17844

Showing the first eight; more decompositions exist.
