Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103824, here are decompositions:

11 + 103813 = 103824
13 + 103811 = 103824
23 + 103801 = 103824
37 + 103787 = 103824
101 + 103723 = 103824
137 + 103687 = 103824
167 + 103657 = 103824
173 + 103651 = 103824

Showing the first eight; more decompositions exist.
