Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103872, here are decompositions:

5 + 103867 = 103872
29 + 103843 = 103872
31 + 103841 = 103872
59 + 103813 = 103872
61 + 103811 = 103872
71 + 103801 = 103872
103 + 103769 = 103872
149 + 103723 = 103872

Showing the first eight; more decompositions exist.
